With tap and go, you simply tap or hold your card or device on the merchant’s payments reader to complete the transaction. How does tap and go work? Tap and go works quickly and seamlessly today thanks to an innovation dating back decades: radio frequency identification, or RFID, a technology that uses radio waves to transfer data.A contactless smart card is a card in which the chip communicates with the card reader through an induction technology similar to that of an RFID (at data rates of 106 to 848 kbit/s). These cards require only close proximity to an antenna to complete a transaction. How Contactless Credit Cards Work. Contactless credit cards have a small embedded chip emitting electromagnetic waves. This chip is not the “insert” chip you use instead of swiping.Tapping to pay uses short-range wireless technology to make secure payments between a contactless card or payment-enabled mobile/wearable device and a contactless-enabled checkout terminal.

How do contactless credit cards work? Transactions are encrypted: Just like with a chip card, each transaction is accompanied by a one-time encrypted security code that dynamically authenticates your payment information.
Contactless payments operate either through cards or through mobile apps and digital wallets. These payments typically use either radio-frequency identification (RFID) or near field. Instead of inserting a credit or debit card into a merchant payment terminal, contactless credit cards rely on radio frequency identification technology (RFID) and near-field communication to complete a retail transaction. Card readers emit radio waves. When a card is placed close enough, the reader is able to send transaction details. The card’s microchip returns a signal, responding with payment details so the transaction can be processed.
