Operations in Vending Machine – a Closer Look

vendnetusa - Operations in Vending Machine – a Closer Look

A vending machine provides customers convenient access to snacks, drinks, personal supplies, and many other items for use or consumption. Vending machines provide operators with income that can serve as a full-time job, part-time job, or side hustle

This article provides an overview of how vending machines operate.

Journey of a remarkable innovation

Vending machines are a highly sophisticated product today, but their beginnings were humble yet marked. The first-ever traces of the vending machine was in 215 BC, when Hero, the mathematician, developed a device that dispensed holy water in the temples of Alexandria in exchange for bronze coins. In the AD 1000s, the machine began finding its real purpose.

Beverage vending machines were first used in Paris, France, during the 1890s to dispense cigarettes and liquor. Today, vending has evolved to dispense hot and cold beverages, hot and cold foods, flowers, clothing, postage stamps, books, movies, company assets, and much more.

The earliest instance of vending machines in the United States was in 1896 when the Adams Gum Company introduced gum machines, which were placed on elevated train platforms across New York City. Cigarette vending machines were first brought into the picture by William Rowe. 

In 1931, F.A. Wittern, Sr. began operations. The Wittern Group now has a storied history in the convenient services industry. We had begun vending operations even before coffee vends were first developed in 1946. Vendnet, a subsidiary of the Wittern Group, is one of America’s leading establishments in vending machine service. 

A brief on the fundamentals

We know how vending machines work – users deposit payment through cash or other means, and the machine accepts the payment and dispenses the required food or beverage to customers. This machine is intricately designed, with each layer of the design serving a purpose of its own.

The raw materials involved in vending machine manufacturing include galvanized steel, plastic, acrylic powder coating, and polyurethane insulation. Galvanized steel is majorly used to prevent the machine from rusting, as a rusted device isn’t quite sustainable and hence may result in damage. The thicker gauge of the steel is used for the internal tank and external doors, while the thinner gauges are used to create the interior doors and plates.

Acrylic powder coatings, painted on vending machines’ surfaces and then baked during production, can make the device smoother and resistant to natural conditions and chemicals. Polyurethane foam is used to insulate the internal portions of the machine and help maintain the optimal temperature required for proper operation.

A closer look

A design so meticulous should constitute a range of accessories. Here’s a highlight:


The keypad is our means to communicate with this machine. The keypad receives the instructions from the user and transmits the same to the vending machine’s control board.


The tray, on a basic level, stores the product in the vending machine. Motors and coils are attached to the tray to dispense items. Coils are attached to motors with a coupler. The motor powers the coil to turn and release the product.

Bill Acceptor

Bill acceptors receive paper currency and validate bills without human supervision. Once the bill is approved, the bill validator sends a signal to the control board acknowledging payment has been received. The bill is eventually stacked in a holder to be accessed and removed later.

Control Board

This is a central component that manages the entire machine. Its functions are comprehensive and include:

  • Monitoring the status of the machine
  • Organizing security issues
  • Alerting any unauthorized security access
  • Ensuring that the device is server-connected

The Quality Control process

Every machine is rigorously tested after the assembly. These tests are conducted to verify if the stacks are properly fitted in, whether all accessories function well, and if any operational area needs further attention. Products that pass the test will be packed and processed to the market or the consumer point.

Best Practices to Reduce Vending Machine Repair Needs

VendnetUSA - Best Practices to Reduce Vending Machine Repair Needs

The best way to ensure your business is running smoothly is to ensure that the machine is always running steadily, and not experiencing avoidable downtime and repairs. Here’s how to keep your equipment operating well and working for as long as possible, avoiding repairs and improving revenues.

Follow these simple vending machine maintenance tips: Regular maintenance is one of the most significant ways to lessen the likelihood of vending machine repair needs. If you know how to fix devices, you can save money. However, everybody should be aware of the machine’s maintenance procedures to keep it in excellent operating condition and avoid significant challenges.

Easy Steps to Maintaining a Vending Machine:

  1. Ensure Better Positioning: To maximize ventilation and limit the danger of overheating, keep vending machines at least 4 inches away from walls. Overheating and UV discoloration may be avoided by keeping your vending machine out of direct sunlight. Also, make sure vending machines are perfectly balanced on the ground.
  2. Proper Plug-in: Most providers get calls claiming a vending machine they installed isn’t operating. Most of the problem is mainly because the equipment has been disconnected from its power supply. Sometimes all it takes to fix a vending machine issue is re-plugging it.
  3. Keep it Clean: To eliminate dirt and bacteria, wipe down and clean surfaces regularly. Clean the condenser coils using compressed air or a brush every 3 months, depending on the site’s cleanliness. Depending on usage, clean all accessible portions of the vending machine at least twice a year with mild detergent, warm water, and a soft cloth. Using compressed air to clean the condenser coils regularly extends durability. The lifespan may extend if your machine is placed in a cleaner environment.
  4. Clean the bill acceptor: This portion may be cleaned with a moist cloth or disinfectant wipe. When a consumer makes a purchase, this is the most crucial portion of the vending machine since it helps to check and read the cash value. Cleaning can assist in lessening the likelihood of money being trapped.
  5. Periodic Check: Checking the voltmeter and ammeter, as well as the machine’s voltage and ensuring that the correct amount of power reaches the machine will significantly extend the machine’s life.

Choose vendnet that lets you order parts, provides technical support and a variety of instructional videos that help troubleshoot. Also, keep in mind that the manufacturer of vending machines must provide documentation on spare parts and procedures to maintain the machines functioning smoothly.

Vending Machine Service And Repair – A Complete Guide

VendnetUSA.com Vending Machine Service And Repair - A Complete Guide

If you have a vending machine in your business, you want it to work as intended. Not only is it an inconvenience for you and your customers if it breaks down, but you also lose out on sales. There are certain vending machine repairs that you may handle yourself rather than spending time and resources on technical support. 

Minor challenges to deal with in a vending machine. Here are a few minor issues that you may fix without the need for technical support. 

  • Improper Ventilation: A vending machine requires airflow. It’s best to keep it 5-6 inches away from the wall. Because some beverages, such as diet drinks, can freeze at high temperatures, make sure the thermostat is set appropriately. Temperatures of 35-40 degrees Fahrenheit are recommended. If a machine occasionally jams, it’s almost certainly due to temperature.
  • Stuck Coins: First thing to do is to see if any slots are empty. If the items are not present, the machine will return the money to the vendor, indicating that there is a jam. If items are available, you must clear the blockage if coins are not returned. Remove all cans and other goods before replacing them. Also, make sure the wheels are in good functioning order. These two critical checks should solve the issue. 
  • Not accepting bills: If your vending machine refuses to accept bills, there are two possibilities. There isn’t enough change in the machine, or the dollar validators are damaged. You’ll likely need to replace any loose dollar validators. Check it two or three times to make sure it’s operating correctly.

Vending machine maintenance is crucial and periodic checks have numerous advantages. All the little inspections will simplify your vending machine operation while saving you time. Routine inspections will reduce downtime, which will help your company gain a good reputation. 

There’s a lot you can do to ensure your vending machines are running at full capacity for as long as possible. In case of difficulties before contacting a professional, we recommend trying a few things to fix your vending machine on your own. 

Test to see if all the selections are working

When a food or beverage is selected, it is intended to drop down within seconds. If it doesn’t, be prepared for one disappointed customer.

You may wonder who appears to be the culprit of this unfortunate incident. There might be several reasons, but the most common is a defective motor. Make sure you test each product you choose. Press every motor switch to discover if a single-engine is faulty or if the machine as a whole is malfunctioning.

Perform an immediate power check

Although it may be a simple task, many vending machine operators fail to check the power supply. If the power supply for your vending machine is an issue, keep in mind that it features dollar bill slots, coin mechanisms, and control boards that all require electricity to operate. The device will not work if the circuit is tripped or the cable is disconnected.

Before you do anything, make it a practice to examine the product first. You don’t want to waste money on unnecessary expenditures only to discover that the connections are the only ones at fault.

Keep vending machines level during repairs

Positioning the vending machine on a flat surface is another easy repair for the most frequent vending machine problems. Otherwise, the entire vending process may be disrupted, resulting in products not dropping down. It can also prevent you from making necessary changes to the vending machine. 

Ensure the money path is clear 

The money mechanics of these vending machines will become soiled with everyday use. When cash and coins are inserted into the machine, filth and dust are left behind, accumulating over time.

To avoid difficulties, make sure you clean the money slots regularly. This can be done by using a paper towel or a damp cloth. Remove the top half of the coin slot to make clearing it more manageable and ensure the passage is free. If you don’t, your coins could get struck and your purchases may be rejected. When should the money pathways be cleaned? Cleaning them every time you collect your earnings is a good practice.

Organize items appropriately

Many vending machines have drinks or snacks that drop when you select them. It’s not adequately organized if they don’t drop down smoothly. Remove the motor cover and press each motor switch one time to test the selection. This starts the vending machine so you can observe whether there’s a problem with one of the motors or the machine itself.

When Should You Call a Professional?

It’s alright to admit failure and ask for help if you’ve tried a few things and nothing appears to be working. Calling experts who can maintain and repair your vending machines are readily available. While most fixes are easy, others may be beyond your knowledge or capabilities. When that time arrives, take a step back and let the experts look into it so you can get your vending machine back up and running quickly.

Vending machine downtime and its impact on your vending business

Vending Machine Downtime - VendNetUSALike all machinery and equipment, vending machines are susceptible to failure or performance issues. While some parts of the machinery are pretty complex and need expert handling, most of them are easy to maintain with low technical skills. In other words, timely DIY maintenance of vending machines can keep the downtime to a minimum.

Meant-Time-Between-Failures (MTBF) is a crucial measure that defines the productivity and uptime of machines. The longer the MTBF is, the better the utilization of the machine will be. When the MTBF is low, however, it is not just a question of machine utilization. Unplanned downtime can impact a vending business at several levels.

Impact on revenue and competition

The point of value creation in the vending business is the vending machine. When it is out of action, consumers cannot buy from it. This translates to a direct loss of revenue. Frequent outage means that the vending machine is standing idle. Suppose your competitors have placed machines in the same location. In that case, your revenue will start flowing into the hands of your competition. This allows your competition to price higher and earn more per machine.

Unrecovered capital

Vending machines are capital equipment. Businesses invest in them and recover the capital over the machine’s life. An idle machine will result in a longer duration to recover the capital employed. Unrecovered capital could bite you harder if your business has multiple machines installed in different locations. The higher the number of transactions, the quicker is your RoCE (Returns on Capital Employed). Ensuring that the machine does not go out of service is essential to achieve this milestone faster.

Cost of upkeep

Machines that fail frequently need constant investment in maintenance and upkeep. The failure could be because of several reasons, including user abuse, ambient operating conditions, lack of proper preventive maintenance or even ageing equipment. Getting the machine back up and running will require investment in parts, consumables, and time of skilled personnel.

Lost customer base

Customers who cannot transact with your machine when they are out cold will look out for nearby alternatives. If a competitor’s machine is available, they will use that machine. When this happens frequently enough, the end-user will eventually start walking straight to the machine they know will work for sure. Over time, frequent outages of your vending machine will lose its customer base.

The loss of  trust from partners

The businesses where you place your machines are your partners. They have chosen to share access to their customer base with your vending business. Hence, they will expect your vending machines to deliver the best experience for the end customer. If they realize that some vending machines serve their customers better than others, they will want to do more business with them than those that are always out of action.

Causes of downtime

A vending machine under repair can do more damage than just losing revenue from a few transactions. This can be easily avoided by taking necessary corrective actions. To take such steps, however, it is required to understand what causes the failure of vending machines. Some of those reasons are discussed below:

  • Machine repairs

All types of machinery experience wear and tear during their operations. Vending machines are no exception to this. Moving components, like the dispensing mechanism, can experience friction-related damages. Electronic components might fail due to power surges. Even simple mechanisms like doors in the collection tray can rust over time. Used machines may come with parts that are past their useful life. User abuse can also lead to repairs that can bring down a good machine.

  • Stocking issues

Another common cause of vending machine downtime is the problems due to poor stacking. Products that come in bags, like potato chips, are a good example. The bags tend to get stuck in the side rails between coils or under the coils. A candy bar on the metal coil can jam two bars and render the whole line useless. A common mistake that most operators make is not checking each product for a successful vend after stocking.

  • Site conditions

Vending machines that store beverages or other refrigerated products are vulnerable to ambient conditions. Too much exposure to the sun might overload the refrigeration compressor. A dusty environment can clog up the air circulation system and choke the refrigeration system. Poor flooring can also result in the machine tipping over. Chocolate bars tend to melt in hot conditions and get stuck in the machine. These are examples of how ambient conditions can cause vending machine failures.

Preventing unplanned downtime in vending machines

Regular preventive maintenance can reduce machine outages significantly. Using the right parts can help you increase MTBF. Operating the machine to specifications can reduce failures due to overloading or mishandling. Ensuring the availability of stock can eliminate instances of idling machines.

Our experts at Vendnet can help you with technical inputs on maintaining a well-oiled fleet of vending machines. We can help you find the right parts and consumables that extend the life of your machines. If you would like help solving frequent machine failures, talk to us at 1-800-833-4411.

Coffee & Hot Beverage Vendors – Clearing Jams in Bill & Coin Collectors.

April VendNet BLOG

Beverages have become an essential part of today’s work culture. Even project modules are broken down based on the amount of coffee involved. For most, a cup of coffee is a routine set in place to begin your day. You visit the coffee vending machine and “clink,” dunk your coin, and “whoosh” comes the beverage of your choice. It all seems so easy.   

Not always! There are countless reasons that cause the occasional hiccup in the local coffee vending machine. And much like an uncontrolled nuclear reaction, when the vending machine comes to a grinding halt, it leads to a chain reaction that ultimately ends with frustration and despair. 

Making sure that employees have access to the elixir is not really that difficult, though. Timely and periodic maintenance is the solution, similar to many other problems.  That is why it is necessary to learn ways to enhance and maintain your vending machines, especially your coffee vending machines. 

In this blog, we take a look at some of the common troubleshooting steps for clearing jams in coins and bill collectors that can create unwarranted drama around the caffeine corner. 

Clearing Jam in Coin Acceptor

There can be several reasons that may cause a jam in a Coin Acceptor. Wear and tear over the years, accumulation of debris, and blockage due to foreign objects can all hinder the normal functioning of the overall system.

A Red DIS flashing: Indication of possible obstruction in the coin discriminator 

If you come across a red DIS flashing light or cannot take coins from your Conlux MCM model coin mechanism, you may have encountered one of the possible scenarios that would require opening up a few of the parts.

A simple workaround is to gently open the cover behind the coin channel to examine for coin jams, obstruction, or other debris. If found, you could remove the block by sliding your finger across the coin channel. You’re good to go! 

Obstruction Beyond the Coin Channel Neighborhood

For obstructions in other parts of the coin mechanism, open the coin funnel and open the acceptor gate to clear out any obstacle you may find.  

Inspecting the Coin Cassette 

Periodic inspection of the coin cassette for obstruction or any misalignment is a healthy practice. Push down on the white finger tap to open the coin cassette. Ensure that the white slider is in the cassette and not lodged at the bottom of the mechanism. 


If the coin jam issue persists, you may have to remove the coin discriminator portion from the coin mechanism to examine other jams.

Clearing Jam from the Bill Acceptor:

Like the Coin Acceptor, you may occasionally have to clear note jams from the bill acceptors. Let us look at some common troubleshooting steps to help fix note jams.

Locating the Bill Collector 

Accessibility to the bill acceptor will vary based on the model of the vending machine. Ideally, you may require a manager pin or a passcode for access. The bill acceptor is housed inside the door. The number of light flashes across it indicates the issue with the bill acceptor.

Diagnostic Indicators
The varying rate of LED flashes points to the possible issues with the bill acceptor. For instance, continuous, slow flashes indicate failure of the unit and the need for replacement. Similarly, fast and continuous flashes mean that the stacker is full.


The first step is to unhook the LED housing from the main unit. Press up the metal pin and pull it outwards. Now inspect the unit for any debris or obstruction that could possibly be causing the jam. If any, remove the obstruction and hook the unit back in.


Locate a blue button on top of the bill acceptor. Push the blue button on top of the bill box toward the door to remove it. Inspect the compartment for jams in both the validation and the box. Flip open the blue color doors and check for any obstruction.



Normally, the steps should help clear out any obstruction and get the machine up and running. In the unlikely event that the self-troubleshooting doesn’t work, then you may reach out for additional support to Vendnet through 1-800-833-4411.

Extending the cashable life of your vending machine in 5 easy steps.

VN March BLOG BANNER_VN Blog Banner Dec

The vending business is a rewarding venture. A major share of the fixed cost goes into buying the machine. There and onwards, the cost is just variable. This means you incur these costs as you make sales. Hence, the recovery of this capital is what defines the breakeven point in a vending business. All the money you make from the machine after your break-even point contributes to your profit. That is why it is important to have a machine that has a long life.

Like all machines with moving parts and user interfaces, vending machines go through wear and tear. If you take good care of your machines, they will keep giving you success and happiness. Yes, we are talking about vending machines, not relationships. Thankfully good machines are designed in such a way that makes their upkeep easy. The key to a long cashable life of a vending machine lies in the following five steps.

1. Preventive Maintenance

Regular maintenance of the machine and its subsystems can help prevent unplanned downtime. Remember, downtime does not only mean spoiled drinks or stale snacks. The true cost of downtime is lost revenue and dissatisfied consumers. Periodic maintenance is not as difficult as it sounds. Some basic checks like cleaning blocks in the cash or coin validators and dusting the air intake can help significantly. The videos below show how you can do them both.

Cash or Coin Validator Check

Dusting the Air Intake

2. Upgrade & Update

Technology in the vending space is growing rapidly. Cashless and contactless payments were cutting edge a few years ago. Today, they are no longer a wow factor. You just need them to stay relevant. The demographics of vending machine users are also changing fast. The millennials do not carry their disposable income in cash or cards. They use mobile payments for transactions.

Touchscreens are quickly replacing push-button keypads, as they give the user a better experience. With fewer mechanical parts, they are also more reliable. The pandemic has also created a need for safe contact surfaces. UV irradiation technology can help alleviate some of those concerns. There are several other retrofit options that you can buy and fit on your machines to make them relevant for the changing dynamics of the market. You do not need to fork out cash to buy a new machine each time. These small upgrades are not only cost-effective they also increase the addressable audience for your machine and make them more profitable.

3. Reliable Parts & Consumables

Machines are designed, tested, and certified for how different components and consumables come together to meet functionality or safety specifications. This makes it important to use the right parts with the necessary certifications. You can avoid unnecessary machine failure or safety incidents by using certified parts. If you consider the cost of Mean-Time-Between-Failures (MTBF), the savings you make from buying spurious parts will seem trivial.

4. Professional Service & Support

Regular maintenance can be done by the machine owner or its operator. You still need to follow the user manuals and service guide for your machine. However, when your machine is in trouble, ask for help. Call the manufacturer or a reliable support partner. The vending machine is an intricate contraption. It is an electro-mechanical device with many auxiliary pieces of technology, like embedded electronics and cloud connectivity. Making a change in one component can and will impact others, too. While DIY is all the rage today, the value of expertise and experience can never be replaced. Your solution provider might still provide guidance on the phone if the issue does not warrant a visit. But that will definitely be much more informed and safer than getting adventurous with a complex piece of equipment.

5. Customer Satisfaction

Technology like Guarantee Vend can ensure that products are either dispensed successfully, or the money is returned, without exception. This makes your machine more reliable and the experience less frustrating for your customers. In return, the customers treat your machine with the courtesy it deserves. 

A stuck product is frustrating for both the user and the machine operator. It not only results in a failed transaction but the machine is also incapacitated. Following simple instructions while stocking the machine can help avoid frequently failed transactions. This video throws some light on best practices to follow while stocking your machines.

6. Sustainable Profitability

The cost of buying a vending machine is the biggest expenditure while you start a vending business. Suppose you are already running a fleet of machines in different locations. In that case, the cost of owning and operating them is quite high. This includes costs like energy consumption, repairs, maintenance, upgrades, and others. Either way, these five steps can help you enjoy sustained profits.

Taking care of your machines is easier with the right solution provider, like Vendnet. Vendnet provides parts and supplies for a wide range of machines and applications. To know how we can help you enjoy sustained profitability, call us at 1-800-833-4411.

How can preventive maintenance of your vending machines help you sleep better


Why Preventive Maintenance For Your Dispensing Machine?

Dispensing machines are tough cookies. They can handle everything from tampering attempts and inclement weather conditions to unintended product abuse. Yet, they need to be inspected, calibrated, and serviced at the appropriate intervals to ensure minimal downtime and a great experience for the customers. 

What Are The Advantages Of Preventive Maintenance?

  • Fewer/No Breakdowns – a well-maintained machine has fewer chances of halting operations mid-vend during peak traffic hours.
  • Reduced Repairs & Services Costs now, we could imagine that rare scenario where repairs are needed. A routinely checked machine will have you coughing up far less in terms of spare part replacements.
  • Consistent Customer Experience – your dispensing machine plays multiple roles for recurring visitors. You must help maintain the same levels of efficiency for customers as the day you unwrapped the vendor.
  • Increased Cash Flow & Profits – All of these add up to a reduced bottom line and more topline. 

What Tasks Are Covered Under Preventive?

  • Perusing Product Literature: Checking the product and service manuals is the easiest and most effective first step towards preventive maintenance. Even if you do not read it cover to cover, some call-outs are intended to be at the top of your mind. 
  • Maintaining Logs: Checklists require updated data to be compared against to be effective. Logs are the answer here and go a long way in helping with preventive maintenance. Logging also helps keep track of high-impact factors such as water consumption, units of electricity consumed, the time taken to vend items, etc. This approach helps address many avoidable and recurring problems by – 
    • Understanding Cause & Effect: If your coffee dispensing machine requires more water for the same number of vends, the filters likely need to be cleaned. 
    • Identifying Deviations: maintaining logs helps identify the sweet spot in terms of running costs and helps flag down deviations. For example, consider a 29 Selection combo vending machines that require 216 electric power units for 24/7 operations in a month. If your consumption exceeds this substantially, this needs to be checked out.
  • Order Original Parts: Vendnet is your trusted supplier of quality spare parts, and there are few if no parts that we do not have in stock.  
  • Track Feature Usage: Operational wear and tear impacts components differently. For example, the coin validator, motor mechanism, etc., must be checked more frequently than others. 
  • Bringing In Expert Help: dispensing machines are a long-term investment, so it would be best if you were confident about the technicians who worked on them. Vendnet is at your disposal with its 90 years of experience in servicing dispensing machines.

What Is Preventing You From Doing Preventive Maintenance?

However, the biggest question is what exactly prevents you from doing maintenance activities. Is it bandwidth, maintenance costs, access to information, or would you like to see a more compelling business case to invest in preventive maintenance?

Whatever the case is, we highly recommend you get in touch with us because –

  1. If the reason is time or bandwidth – our training videos cover multiple aspects of preventive maintenance in setup videos, certainly worth your time.

The refrigeration equipment is a critical component of your vending machine. When they are not performing their best, they can affect both the consumer and the machine owner. Consumers buying beverages do not want a tepid bottle, they want their drink served cold. Inefficient refrigeration equipment may consume more energy or may eventually fail. This will cost owners more to own and operate such machines, so timely maintenance of the refrigeration deck is in everybody’s interest.

Maintaining the refrigeration unit regularly is not as difficult as it sounds. With a brush, clean the air intake grill from the outside once a week to remove any dirt or dust that may be sticking on. You can watch how to do this HERE.

The air intake coils or condenser need to be cleaned once every two to four months. It is usually located at the bottom of the machine, and can be accessed from the front or back, depending on the model. You will see a metal plate with holes or slits for air intake. You first need to take this part off, either by lifting or by unscrewing. Remove accumulated lint with a medium to hard bristled brush. For a thorough cleaning of the finer particles of dust and dirt, use compressed air. Once you finish cleaning, place the kick-plate back to where it was.

Air Filter

Air filters are often underrated in their significance. If they are not cleaned regularly, they can clog up the airflow, resulting in poor efficiency. This can result in the overheating of your equipment. When the suction is strong enough to bypass the clogged-up air filter, it dirties the heat exchange coil making it less efficient. Periodic clean up of the air filter can help you avoid frequent repairs and downtime.

The air filter is in the lower right-hand corner of your machine. Open the door and gently pull out the filter. Hold it under running water to wash off the collected dust or grime. Hold it in the sink to let the water run off the filter, and then shake it vigorously to remove residual water. Once this is done, put the filter back in its place. This quick video explains how you can do it.

Bill Validator and Coin Unit

You need to clean the bill validator and coin unit every one or two months, depending on the frequency of use. First, shut off the power to the vending machine. Second, take out the cash tray, which is normally situated at the back. Use a dry cloth to wipe it thoroughly and clean it. After that, take out the sensor tray – it may be above or below the cash box. This can be released by pressing two buttons on either side of the tray. This may need to be wiped as well, and if it’s too dirty, moisten the cloth in soapy water and wipe. Make sure that the tray is completely dry before you put it back in the machine. To ensure optimal operation, fill the coin unit tubes up to 2/3 capacity. You can clean this every time you clean the cash tray.

The payment systems are the most important parts for the vending machine owner or operator. It is what a cash register is to a convenience store. When these parts are damaged, they may not be able to collect payments or dispense change properly. Regularly check these parts for breakage or cracks, so that you can get them replaced on time and avoid disruption of Different machines may have different designs for bill validators, but this video shows a common process you should follow to detach for inspection.

Replacing the Barrel Lock

To replace the barrel lock, unlock the door and pop out the handle – you may need a small screwdriver to do this. Turn the handle a couple of times to the left and insert the key. Twist it to the right, and with a screwdriver, press down on the lock on the inside of the handle, and pull it out completely. To install the new lock, open the machine, place the T handle in the correct position, and insert the key with the lock all the way in. Listen for the click; now you know it is in place. Test the handle to check if it’s working before closing the machine door by unlocking it.

Drink/Snack Vending Mechanism

Whenever you load new products, it’s a good idea to check that the machine is vending the items properly – so we recommend checking it once every 60-90 days. Enter the service mode by pressing the button on the front and do a test to check if it is vending properly. Normally, the problems happen with drinks because of the weight of the bottles or cans. It  would be wise to test with a couple of bottles and cans to make sure everything is working as it should. If it gets stuck, check the binding in the delivery mechanism. This will tell you whether the gears in the motor are faulty, if the product is loaded properly, or if the sold-out sensors are malfunctioning.

Improving your machine’s payment system

Thanks to advances in technology, education, the global pandemic, and greater awareness about the spread of contagions, cashless payments are increasing in popularity across the world. Today, most companies prefer to pay their employees through direct bank transfers – though some still pay by check. This also makes it more convenient for consumers to use their cards or e-wallet/mobile wallet to make purchases. It is also safer because even if they lose the card, they can block the card to prevent usage, unlike losing cash or coins. This means that for any business to do well, you need to offer multiple payment options. This applies to vending machines as well. Here are some interesting statistics:

  • In 2020, contactless or mobile payment transactions in the US, crossed 180 billion dollars, and this is expected to more than double in 2023, to cross 370 billion dollars.
  • 44% of online shoppers used credit cards, followed by 32% people who used debit cards – meaning that card payment is still very popular
  • Sales from digital payments (cards, contactless cards, and mobile) in vending machines gradually increased during 2019, and finally surpassed cash purchases in April 2020.
  • A study conducted by Michigan State University said that vending operators who averaged $2000 a year in sales, experienced a jump of 110% after adding cashless technology, in the first 18 months. Interestingly, it also increased the cash sales in those machines.

Of course, this does not mean that cash transactions don’t take place at all, as not everyone has changed.  A lot of people still use cash – though it is more popular among the older generation and in smaller towns.

Today if you want to increase the sales in your vending machine, it is essential that you provide multiple payment options to your customers. At Vendnet, we are the one-stop shop for all of your vending parts, support, and service needs.

Contactless cards and mobile payments are even safer than the magnetic strip cards, as it means you don’t have to touch the surface of the machine.
