Buying a contactless vending machine is the simplest way to stop losing sales to customers who no longer carry coins. This guide covers what to check before you buy, what it costs in the UK, and where a card-ready machine earns the most.

Already own a machine and just want to add a card reader? Our vending machine contactless payment setup guide walks through the retrofit process. This post is for buyers choosing their next machine.

What is a contactless vending machine?

A contactless vending machine accepts tap-to-pay cards, Apple Pay, Google Pay and smartwatches through a card reader on the front panel. Most models still take coins too, so nobody is turned away.

The reader connects to the machine through a standard payment port called MDB or Executive. Payments travel over a mobile data SIM, so the site doesn’t need to provide Wi-Fi.

Readers from providers such as Nayax, Payter and Vendman are common across UK vending. The brand matters less than the fees, the support and whether the reader arrives pre-fitted to the contactless vending machine you buy.

Many readers also show a small screen with prompts and receipts on request. That makes the machine feel familiar to anyone used to paying in a shop, which builds trust at the moment of purchase.

Why card payment now drives sales

UK shoppers have moved away from cash faster than most vending machines have. According to UK Finance’s Payment Markets Report, contactless made up 39% of all UK payments in 2025, while cash fell to just 8%.

Mobile wallets are the other big shift. Around 65% of UK adults are now registered for one, rising to 89% of 25 to 34-year-olds.

“A cash-only machine is invisible to a customer with no coins. A contactless vending machine turns that same passer-by into a sale.”

Card payment also lifts basket size. When people aren’t limited by the change in their pocket, they’re more likely to add a second drink or a pricier snack.

It opens up higher-value products as well. PPE, phone chargers and meal deals over £5 are hard to sell by coin, but easy to sell through a contactless vending machine.

Card payments also leave a clear record. Every sale is logged with a time and amount, so you can see your busiest hours, spot slow products and plan restocking around real demand rather than guesswork.

That data is hard to get from a coin-only machine. With a contactless vending machine, you can compare sites side by side and move stock or machines to wherever they earn most.

Built-in reader vs retrofit: which should you buy?

You have two routes. Buy a contactless vending machine with the reader already fitted, or buy a coin machine and add a reader later.

For most first-time buyers, a pre-fitted reader is the safer choice. It’s tested with the machine before delivery, so there’s no second visit and no compatibility risk.

A retrofit makes sense if you already own solid coin machines. It’s cheaper than replacing a working machine, as long as the payment port is compatible.

One practical point: older machines sometimes need a firmware update or a replacement control board before a reader will work. Ask for the model number and year, and get the full retrofit cost confirmed before you choose that route over a new contactless vending machine.

If you run several sites, a mix often works well. Put a pre-fitted machine where footfall is highest, then retrofit the older coin machines at quieter sites as budget allows.

Card-only or card and coin?

Some operators now buy card-only machines. Removing the coin mechanism means no cash collection trips, no jammed coins and nothing inside worth breaking in for.

The trade-off is reach. A card-only contactless vending machine will miss the minority of customers who still pay with coins, and that minority is larger at some sites than others.

For most first machines, card and coin together is the safer starting point. Once your sales data shows how few coin payments you take, you can decide whether the next contactless vending machine you add needs a coin mechanism at all.

Security is the other factor. A machine that holds little or no cash is a less attractive target, which matters at unstaffed sites and anywhere open overnight.

Types of contactless vending machine

Card payment works on almost every kind of machine. The right contactless vending machine for you depends on what your site needs and how much space you have.

Snack machines

Spiral snack machines are the classic choice for offices, schools and warehouses. A contactless snack machine lets you sell crisps, chocolate and protein bars at prices that don’t need to match the coins in someone’s pocket.

Drinks machines

Chilled can and bottle machines suit gyms, sports centres and anywhere people get thirsty fast. Drinks are often an impulse buy, so a quick tap matters more here than almost anywhere else.

Combo machines

A combo contactless vending machine sells snacks and drinks from one cabinet. It’s ideal for smaller sites that only have room for one machine but want to offer a full range.

Coffee and hot drinks machines

Bean-to-cup and instant machines work well in offices, garages and waiting rooms. Hot drinks often sell above £2, which is exactly where card payment beats coins.

Fresh food and specialist machines

Fresh food, meal deals, PPE and phone accessories usually cost more than a snack. These higher prices make a card reader essential, because few customers carry £5 or £10 in coins.

Whichever type you choose, check the reader is fitted and tested before delivery. Every contactless vending machine in our vending machines for sale range is ready to take cards on day one.

7 critical checks before you buy a contactless vending machine

These are the questions that separate a good contactless vending machine from an expensive mistake. Run through all seven before you commit.

1. Payment options

Check the reader takes contactless cards, Apple Pay and Google Pay. Keep a coin mechanism too if your site has visitors who still prefer cash.

2. Mobile signal

Readers need mobile data to approve payments. Check the signal at the exact spot the machine will stand, not just at the front door.

3. Reader fees

Most readers carry a monthly service charge plus a small fee on each transaction. Get both figures in writing so you can work out your real margin.

4. Telemetry

Many readers report sales and stock levels to an app. That cuts wasted restocking trips and shows which products actually sell.

5. Machine type

Match the machine to the site: snacks, drinks, combo, coffee or specialist stock like PPE. A card reader can’t rescue a machine selling the wrong products.

6. Warranty and support

Ask what’s covered, for how long, and who fixes the reader if it fails. A contactless vending machine that can’t take cards loses most of its sales until it’s repaired.

7. Delivery and installation

Vending machines are heavy and need a proper power check on site. Confirm whether delivery and installation are included in the price.

Contactless vending machine costs in the UK

The price of a contactless vending machine depends on its type, capacity and condition. Refurbished snack and drinks machines cost far less than new coffee or fresh food units.

As an example, our PPE Essentials Vending Machine takes both coin and card and costs £1,995, with delivery and installation included. You’ll find current prices for every in-stock contactless vending machine on our vending machines for sale page.

Budget for running costs as well as the purchase price. The main ones are reader service fees, transaction fees, stock, electricity and occasional servicing.

On a contactless vending machine from Irelley, card payment with telemetry costs £10 a month plus 2% per transaction. That one price covers taking cards and seeing your sales and stock levels from your phone, so your contactless vending machine is ready to earn from day one.

If the up-front cost is a hurdle, you can spread it. Our vending machine payment plans let you pay monthly while your contactless vending machine starts earning.

How much can a contactless vending machine earn?

Earnings depend far more on the site than on the machine. Footfall, opening hours, product mix and pricing all matter more than the brand of reader on the front.

What card payment does is remove a reason not to buy. A customer with no coins can still buy from a contactless vending machine, so more of the people who walk past become sales.

Here’s a simple way to think about it. If a machine makes £400 a month and card payment adds even 10–20% more sales, that’s £40–£80 extra a month. On Irelley’s £10 a month plus 2% card rate, the reader cost on £400 of card sales is about £18.

New or refurbished contactless vending machine?

A refurbished machine costs less up front, and many can take a card reader. The catch is that older machines may need a firmware update or new control board before a reader will work.

A new contactless vending machine costs more but arrives with the reader built in, tested and covered by warranty. It’s also likely to use less power and last longer.

If budget is tight, a payment plan can make a newer machine affordable. Our refurbished vending machines buyer's guide explains what to check if you go second-hand.

Best sites for card-ready machines

Card payment matters most where customers are young, busy or passing through. Offices, gyms, universities, hospitals and transport hubs all fit that profile.

Warehouses and factories are a strong fit too, especially for PPE and night-shift snacks. Workers rarely carry cash on shift, and the canteen may be closed.

Sites with older visitors, such as some care homes and community halls, still see more coin use. There, a contactless vending machine that also takes coins is the safest pick.

Whatever the site, place the machine where people naturally pass. Entrances, break areas and corridors to the car park beat a quiet back corner every time.

Before you commit to a site, ask the owner how many people use the space each day and at what times. A contactless vending machine in a building with steady footfall across long hours will outsell one in a busier site that empties at 5pm.

Pricing products on a contactless vending machine

Card fees are small, but they come out of every sale. The simplest approach is to build them into your normal prices rather than charging card users more.

Customers dislike seeing a higher price for paying by card, and many will walk away. Keep one price for cash and card, and let the extra sales cover the fee.

Card payment also frees you from coin-friendly prices. A contactless vending machine can sell a drink at £1.35 or a meal deal at £4.80, so you can price each product for margin instead of convenience.

Review your prices every few months using your sales data. If a product sells out quickly, a small price rise may barely affect demand, while slow sellers may need a cut or replacing.

Finally, check your prices against nearby shops and canteens. People will pay a little more for convenience, but not double what the café next door charges.

Common buying mistakes

The biggest mistake is buying on price alone. A cheap contactless vending machine with an unsupported reader can cost more in lost sales than you saved.

The second is ignoring signal. A reader in a basement with no mobile data will decline cards all day, and customers rarely try twice.

The third is skipping the contract detail. Check the reader’s minimum term, cancellation terms and who owns the hardware if you stop paying the service fee.

The fourth is overstocking on day one. Start with a tight product range, watch the sales data, then expand into what your customers actually buy.

Finally, don’t forget pricing. Customers paying by card are less sensitive to round numbers, so a contactless vending machine lets you price at £1.35 or £2.10 instead of rounding to the nearest coin.

Running a contactless vending machine day to day

Card payment changes how you run your machines as well as how customers pay. With fewer coins to collect, your visits can focus on restocking and cleaning.

Telemetry is the biggest change. A contactless vending machine with telemetry shows sales and stock levels on your phone, so you only visit when the machine actually needs filling. Our guide to vending machine telemetry explains how it works.

Keep the reader clean and check it on every visit. A smudged screen or a faulty reader quietly turns a contactless vending machine back into a coin-only one.

Watch your card data too. If a product sells well at lunchtime and badly in the evening, adjust your stock and restocking times to match.
