What are Contactless Payments?
Contactless payments are transactions made by tapping or holding a payment card, smartphone, or wearable device near a contactless-enabled terminal. They use Near Field Communication (NFC) technology to transmit payment data wirelessly over a short range, without inserting the card or entering a PIN.
How Contactless Works
Contactless payment cards and devices contain an NFC chip and antenna. When held within a few centimetres of a contactless terminal, the chip transmits encrypted payment data wirelessly. The transaction is authorised by the card network and issuing bank in the same way as a chip-and-PIN payment, but without the need to insert the card or enter a PIN.
Contactless Limits
In the UK, the contactless payment limit is £100 per transaction. For amounts above this, the customer must use chip-and-PIN. Some card issuers also require periodic PIN verification after a number of consecutive contactless payments as an additional security measure.
Mobile Contactless
Smartphones and wearables (Apple Pay, Google Pay, Samsung Pay) use the same NFC technology but with additional security. Mobile contactless payments require biometric authentication (fingerprint or face recognition) or a device PIN before each transaction, and have no spending limit in most cases.
Contactless Security
Each contactless transaction generates a unique cryptographic code, meaning the data cannot be reused for another transaction. The card number transmitted wirelessly is different from the actual card number (tokenisation), adding another layer of protection.
Contactless payments handle in-person transactions. Paytia handles the remote payment channels — phone, chat, and payment links — where contactless is not possible. Together, they give businesses complete payment coverage across every customer interaction.
Frequently Asked Questions
Are contactless payments safe?
Yes. Each transaction uses a unique encrypted code that cannot be reused. The card number transmitted is tokenised. And the short NFC range (a few centimetres) makes interception extremely difficult.
What is the contactless limit in the UK?
The UK contactless limit is £100 per transaction for physical cards. Mobile contactless payments (Apple Pay, Google Pay) typically have no limit because they require biometric authentication.
Can I accept contactless payments over the phone?
No — contactless requires physical proximity between the card and terminal. For phone payments, businesses use DTMF masking or payment links to capture card details securely without the customer being physically present.
