Chip and Pin vs Contactless vs Mobile Payments: What’s the Difference and Which Is Best for Your Business?
Walk into any UK shop, pub, or market stall today and you will see all three methods being used side by side. Customers tap their card, insert their chip and pin, or wave their phone at the reader depending on what they have to hand and what the situation calls for.
For business owners setting up a card machine for the first time, or reviewing their current setup, the question is not which payment method is best for customers. It is which combination your card machine needs to support, whether they all cost the same to process, and whether any of them come with risks or limitations worth knowing about.
This guide answers all of that in plain terms.
What is chip and pin?
Chip and pin is the payment method where a customer inserts their card into the terminal, the chip in the card is read, and the customer enters their four-digit PIN to authorise the payment. It replaced the old swipe-and-sign method across the UK in 2006 and remains the most secure way to take a card payment.
The key advantages of chip and pin for businesses are that it carries a lower risk of fraud-related chargebacks, there is no transaction limit, and it works for customers who have not set up contactless or who prefer to use their PIN. The slight downside is speed - chip and pin takes five to ten seconds per transaction, which matters in a fast-paced bar or busy checkout queue.
What is contactless?
Contactless allows a customer to pay by tapping their card or device against the reader without inserting the card or entering a PIN. The payment is authorised wirelessly using near-field communication (NFC) technology.
Contactless is now the dominant payment method in the UK. According to UK Finance, more than 60% of all card transactions in the UK are now contactless. The speed benefit is significant - a contactless tap takes one to two seconds compared to five to ten for chip and pin.
There is a common misconception that contactless has a hard transaction limit. While there was a £100 per transaction limit for standard contactless card taps, modern terminals using strong customer authentication can process higher values by periodically prompting customers to enter their PIN to confirm it is them. There is no limit on contactless payments made via Apple Pay or Google Pay, which use device-level biometric authentication.
What are mobile payments?
Mobile payments refer to payments made using a smartphone, smartwatch, or other wearable device rather than a physical card. Apple Pay, Google Pay, and Samsung Pay are the most common examples in the UK.
From a business perspective, mobile payments are processed exactly like a contactless card payment. The terminal does not need any special setup to accept them - if your card machine accepts contactless, it already accepts Apple Pay and Google Pay. The transaction fees are identical to a standard contactless payment.
Mobile payments are growing rapidly, particularly among younger customers and in urban areas. Importantly, they offer very high security because every transaction is authenticated using the customer's fingerprint, face ID, or device PIN before it is processed.

Do the three methods cost different amounts to process?
From a merchant's perspective, the processing cost is determined by the card type and card scheme, not the payment method used to authorise the transaction. A Visa debit card costs the same to process whether the customer taps, inserts, or pays via Apple Pay.
What does affect your costs is the type of card being used:
Debit cards: lowest processing cost, typically between 0.35% and 0.7% on a tiered pricing structure
Consumer credit cards: slightly higher, typically between 0.65% and 1.0%
Corporate or commercial credit cards: highest cost, often 1.5% to 2.5% regardless of payment method
If you are on a flat-rate provider like Square, SumUp, or Zettle, you pay the same percentage on every transaction regardless of card type or payment method. That simplicity costs you money as your volume grows, particularly on debit card transactions which make up the vast majority of UK payments.
Which payment methods should your card machine support?
In 2026, any card machine worth considering for a UK business should support all three as standard. If a terminal only accepts chip and pin, you will turn away a significant proportion of customers who prefer to tap or pay by phone.
When choosing a card machine, look for:
NFC enabled for contactless and mobile payments
Chip and pin as standard for higher-value transactions and customers who prefer it
A screen that clearly shows the payment amount before the customer taps or inserts
Fast processing speed, particularly important in hospitality and retail environments
A reliable connection, whether that is WiFi, 4G, or both
Common questions about chip and pin and contactless
Can I use contactless if I am overdrawn?
This is one of the most searched questions around contactless payments in the UK. The short answer is that it depends on your bank and account type. Some banks allow contactless payments to go through even when a current account is overdrawn, particularly if the customer has an arranged overdraft facility. Others will decline the transaction. The card machine itself has no way of knowing an account is overdrawn - the decline comes from the customer's bank, not the terminal. From a business perspective, a declined contactless tap simply means the customer needs to try another card or payment method.
Is contactless less secure than chip and pin?
Contactless is very secure, but chip and pin carries a slightly lower fraud risk for high-value transactions because it requires the customer to know their PIN. For everyday purchase values, contactless fraud rates in the UK are extremely low. Mobile payments via Apple Pay and Google Pay are arguably the most secure of all, because every transaction requires biometric authentication from the customer's device before it is processed.
What happens if a customer's contactless does not work?
Banks periodically require customers to insert their card and enter their PIN as a security check, even for low-value transactions. This is a deliberate fraud prevention measure rather than a fault with the card or terminal. Your card machine should always be able to fall back to chip and pin if a contactless tap is declined for this reason.
Do I need a special card machine to accept Apple Pay and Google Pay?
No. Any NFC-enabled contactless terminal accepts Apple Pay and Google Pay automatically. No additional setup is required on the merchant side. If your card machine has a contactless symbol on it, it already accepts mobile payments.
What this means for your business setup
The practical takeaway for any UK business owner is straightforward. You need a card machine that accepts all three payment methods as standard, processes transactions quickly, and connects reliably throughout your trading hours.
Beyond the hardware, the bigger decision is your pricing structure. Whether a customer pays by chip and pin, contactless, or mobile makes no difference to your transaction fee. What does make a difference is whether you are on a flat rate or a tiered structure, and whether your provider is transparent about what you are actually being charged.
BoonPay supplies NFC-enabled terminals that accept chip and pin, contactless, Apple Pay, and Google Pay as standard. Our pricing is tiered based on your revenue, with next-day gross settlement included and 7-day UK-based support if anything goes wrong.
