A contactless card is a type of payment card that allows users to make transactions without physically inserting or swiping the card. Instead, it uses radio frequency identification (RFID) or near-field communication (NFC) technology to transmit payment information when the card is held near a compatible payment terminal. This method speeds up the checkout process and enhances convenience for users. These cards are commonly issued by major financial institutions and can be used for various purchases, including groceries, public transport, and online shopping. Many smartphones also support contactless payments, allowing users to make transactions using digital wallets linked to their contactless cards.
