Contactless payment is a technology that allows consumers to make transactions without physically swiping or inserting their payment cards. Instead, users can simply tap their card or mobile device near a compatible payment terminal. This method uses radio frequency identification (RFID) or near-field communication (NFC) to securely transmit payment information. This payment method is popular for its speed and convenience, especially for small purchases. Many smartphones and smartwatches also support contactless payments through digital wallets like Apple Pay or Google Pay, making it easier for users to pay without carrying cash or cards.
