What is an NFC payment?

In short

An NFC payment is a contactless payment in which a card, a phone or a watch exchanges payment data with a terminal over near-field communication, a short-range radio link, when the two are held together. The NFC Forum describes the technology as operating at a base frequency of 13.56 MHz, with a typical range of up to 2 cm.

How an NFC payment works

The terminal generates a radio field. A contactless card has no battery: the field powers its chip, and the two exchange messages under the EMV contactless specifications. A phone or a watch does the same in card emulation mode, presenting a tokenised copy of the card from its wallet.

The chip or the wallet produces a cryptogram for that one payment, and the terminal sends it with the payment details to the acquirer and the issuer. EMVCo describes this as a one-time security code generated for every transaction.

The parts of an NFC payment

  • The device: a contactless card, or a wallet such as Apple Pay or Google Pay
  • The reader: a card terminal, or a phone running SoftPOS
  • The kernel: the terminal software for each card scheme's contactless specification
  • The token: a wallet sends a device-specific number, not the card number
  • The verification: none for small amounts, or a PIN, a fingerprint or a face check

Why NFC matters to a payments product

For an issuer, NFC means provisioning cards into wallets through the schemes' token services. For an acquirer or a SoftPOS provider, it means approved contactless kernels and, in the EU and the UK, the rules on contactless payments made without strong customer authentication.

NFC payment, contactless payment or QR code?

Contactless payment
The payment as the buyer sees it: a tap. NFC is the radio technology underneath.
QR code payment
Uses the phone's camera and an internet connection, with no radio link between the two devices.
