Contactless cards use an embedded computer chip and radio frequency antennae, allowing the cardholder to simply "tap and go" when making a purchase. Contactless transactions are processed through the same, reliable EMV payment network as contact transactions. Contactless transactions only work when a contactless card is used at a contactless terminal. When used at a non-contactless enabled terminal, the cardholder can insert or swipe the contactless card at the terminal.
