What are Contactless Payments and How Do They Work?

Whether you’re a busy café serving the morning rush or a boutique shop handling a bustling weekend crowd, contactless payments have become the backbone of modern commerce. In fact, our research shows that 54% of UK shoppers' favourite way to pay in-store is by contactless.

But what exactly happens when a customer taps their card or phone on your contactless terminal?

We’ll break down the technology behind the tap, and share how the 2026 regulatory changes and the scrapping of the £100 contactless limit are giving businesses more flexibility.

What is a contactless payment?

A contactless payment is a secure method of paying for goods or services without needing to insert a card into a machine or enter a PIN. Instead, customers simply tap or wave their enabled card, smartphone, or wearable device near a compatible reader to complete the transaction wirelessly.

More commonly known as ‘Tap to Pay’, contactless payments first started back in 2007 when shoppers could use them on purchases up to £10 across limited retailers and the Transport for London network. 

It’s evolved a lot since then and has surged in popularity because it’s incredibly quick. It’s often more than twice as fast as standard Chip and PIN payment, making it the most convenient option for 87% of shoppers. 

How does contactless work?

The magic behind the tap is a technology called Near Field Communication (NFC). NFC allows two devices — like a card and a contactless terminal — to communicate over a very short distance, usually just a few centimetres.

When you enter an amount into your card machine, it sends out a radio frequency signal. When the customer brings their card or device within range, the terminal and the card exchange encrypted data to authorise the payment. This happens almost instantaneously, making it much faster than counting out change.

How to tell if a card is contactless

Not every bank card has the technology to tap and go, though it’s the standard now for almost all UK providers. To check if a card is contactless, look for the contactless symbol on either the front or the back.

This symbol looks like four curved radio waves, similar to a Wi-Fi icon turned on its side. If that symbol is present, the card has a built-in antenna and chip that can communicate with your contactless terminal.

The different types of contactless payments

As technology evolves, the way we define a card payment is broadening. Your customers might choose to pay at your contactless terminal via:

Contactless cards

These are traditional plastic debit or credit cards, equipped with a built-in chip and a radio frequency (RFID) antenna. They allow for a physical ‘tap’ on the reader.

While they are the most common form of contactless, they are increasingly being used alongside digital versions stored on smartphones.

Mobile wallets

Apps like Apple Pay and Google Pay store encrypted versions of card details on a smartphone or tablet. They use biometric authentication, like facial recognition or a fingerprint, which adds an extra layer of security and often allows customers to bypass standard spending limits.

Over half (57%) of UK adults are now registered for at least one mobile wallet, also known as an e-wallet, service.

Wearable devices

This includes everything from smartwatches and fitness trackers to even some high-tech jewellery. They work exactly like a mobile wallet, using NFC technology to communicate with your card reader.

They’re perfect for customers on the go, like joggers or commuters, who might not want to carry a bulky wallet or can’t reach for their phone.

SoftPOS

Short for ‘Software Point of Sale’, SoftPOS technology turns a regular NFC-enabled smartphone or tablet into a payment terminal itself, without the need for extra hardware.

For example, solutions like Tap to Pay on iPhone allow small business owners to accept contactless card payments using the tech they already own. This is a great, flexible option for sole traders or mobile businesses.

How to make a contactless payment

Making a payment is designed to be as frictionless as possible. Here’s how it works from start to finish:

1. Enter the amount — The merchant enters the transaction details into the contactless terminal.
2. Check the screen — The terminal will light up or show the contactless symbol, indicating it’s ready to receive a signal.
3. The tap — The customer holds their card or device within a few centimetres of the symbol on the reader.
4. Verification — For phones, the customer may be prompted to scan their fingerprint or face. For cards, the machine will beep and show a ‘Processed’ or ‘Approved’ message when the payment has been authorised.
5. Completion — The terminal prints a receipt (if required) and the transaction is complete, all in a matter of seconds.

What are the latest contactless limit changes in 2026?

The UK payment landscape has undergone a major shift in recent years, and that isn’t stopping in 2026. Historically, the Financial Conduct Authority (FCA) set a hard limit of £100 on single contactless card payments.

However, as of 19th March 2026, the industry is moving toward greater flexibility.

The FCA confirmed in late 2025 that the fixed £100 limit would be scrapped, giving banks and card providers the power to set their own contactless limits. This means that for many businesses, higher-value transactions can now be completed with a simple tap, which could potentially lead to more sales for stores selling higher-priced goods.

Why has this change happened?

The move away from the universal limit isn’t just a coincidence; it was driven by several key factors in the UK market.

• Consumer demand for speed — UK shoppers expect checkout experiences to be quick and seamless, and a hard limit can sometimes act as a barrier to that convenience. 44% of consumers specifically stated that contactless is their preferred method because it’s faster than any other option.
  
  
• Widespread adoption across all ages — Tap to Pay is no longer just for the tech-savvy. Our research shows a massive preference for contactless across the generations, including 52% of 35-44 year olds, and a staggering 62% of those over 55.
  
  
• A shift in ‘pocket money’ habits — The way we carry money has changed; contactless adoption has now officially overtaken cash for in-store payments, with 1 in 2 consumers regularly tapping to pay.
  
  
• Proven safety — Contactless payments are just as safe as using a standard bank card, posing no higher risk than Chip and PIN payments by removing the limitation.
  
  
• Mobile wallet parity — Since mobile wallets already allow for higher-value transactions via biometrics, the change brings physical cards more in line with digital habits.
  
  
• Economic necessity — With the rising cost of goods, a £100 limit can be restrive for a standard weekly shop or a meal out. Flexible limits allow the technology to keep pace with real-world prices customers are facing in 2026.

Are contactless payments safe?

Despite lacking a unique PIN code to complete every transaction, contactless payments are very secure. 

Here’s why it’s a safe way to pay:

• Short-range communication — Contactless cards only work in close proximity, usually a few centimetres, to a payment terminal. This reduces the risk of unauthorised interception or data theft.
  
  
• Reduced physical contact — Without needing to be inserted into a card reader, the chances of the card being copied by a compromised skimming device — a plastic overlay attached to a legitimate POS terminal that scoops information from a bank card’s magnetic strip — are drastically reduced.
  
  
• Tokenisation — This is a security technique where a unique, randomly generated token is transmitted instead of the actual card number. Even if the token were intercepted, it would be useless to fraudsters as it cannot be used outside that specific transaction context.
  
  
• Two-factor authentication — In some cases, transactions may require additional verification. This adds an extra layer of security by requiring a PIN or biometric authentication (like a fingerprint or facial recognition) to prove the cardholder’s identity.
  
  
• Zero-liability policies — Many banks and card providers offer policies that protect cardholders from financial liability in the event of fraudulent transactions.
  
  
• Encryption — All transactions are encrypted to protect the data exchanged between the card and the terminal. This means that payment information remains secure and cannot be easily tampered with during transmission.

The benefits of a contactless terminal

For independent businesses, a contactless terminal is more than just a piece of kit; it’s a tool that can transform your day-to-day operations.

• Faster service and shorter queues — Tap to Pay is significantly quicker than traditional cash or Chip and PIN transactions. By reducing this time to seconds, you can serve more customers in less time, preventing queue fatigue and lost sales during busy periods.
  
  
• Increased customer spending — Removing the friction of counting cash can lead to higher transaction values. Customers could be more willing to make impulse purchases or add extra items to their basket when they aren’t limited by the physical cash in their wallet. In fact, our research revealed that 57% of Brits agreed that contactless payments make them spend more than other methods.
  
  
• Better hygiene and safety — Less handling of physical cash is a big advantage in the hospitality and retail industry. It reduces the risk of spreading germs and keeps your staff and customers feeling safer and more comfortable.
  
  
• Improved customer loyalty — Convenience is a major driver of repeat business. In fact, 15% of shoppers say they wouldn’t complete a purchase if their preferred mobile or digital wallet options weren’t available.
  
  
• Better cash flow management — Contactless terminals provide real-time reporting, allowing you to track your sales and monitor your business’s financial health more accurately. This visibility makes it easier to manage stock levels and plan for the future.
  
  
• Reduced risk of human error — Manual cash handling is prone to mistakes, such as giving incorrect change or errors in till reconciliation. Contactless payments automate the transaction process, ensuring accuracy every time.

How long does a contactless payment take to clear?

The clearing time for a contactless payment typically depends on the payment provider and the bank, but in 2026, real-time payments are becoming the default.

This means the authorisation happens in seconds. The money is then immediately held or marked as pending in the customer’s account.

For the merchant, funds usually clear within 1 to 3 working days. However, with the rise of instant settlement rails, many businesses now see funds in their accounts much faster, sometimes within the same day.

How to know if a phone has contactless pay

For a smartphone to make contactless payments, it needs a piece of hardware called a Near Field Communication (NFC) chip.

• iPhone users — Every iPhone since the iPhone 6 has NFC capabilities as standard.
  
  
• Android users — Most modern Android phones have NFC, but it can be toggled on or off. Customers can check this by going to their settings and searching for NFC.

• The wallet app — If a customer can successfully add a card to their Apple Wallet or Google Pay app, their phone is ready to make contactless payments.

Can contactless payments be declined?

Yes, a contactless payment can be declined for a range of reasons, just like any other transaction:

• Insufficient funds — If there isn’t enough money in the account to cover the cost.
  
  
• Security checks — Banks occasionally decline a tap to prompt a Chip and PIN entry, making sure the right owner is using the card.
  
  
• The limit is reached — If the transaction is above the current contactless limit set by the customer’s bank.
  
  
• Technical issues — If the card is damaged or the terminal loses its internet connection.
