NFC (Near-Field Communication)
Quick Answer
NFC is a short-range wireless technology that enables data exchange between devices when they are held close together, commonly used for contactless payments.
Definition
NFC is a short-range wireless technology that enables data exchange between devices when they are held close together, commonly used for contactless payments.
Explanation
NFC allows two devices to communicate when they are within about 4 centimeters of each other. In payments, NFC enables contactless transactions by transmitting encrypted payment data from a card or phone to a payment terminal. NFC is also used for transit cards, access badges, and data sharing.
NFC payments are more secure than magnetic stripe cards because they use tokenization and require close proximity, making them harder to intercept. Most modern smartphones and payment terminals support NFC.
Example
A customer taps their contactless credit card or phone on a payment terminal to pay $15 for coffee — the transaction completes in under a second without inserting a chip or signing.
