A contactless card, also known as a “ tap-to-pay ” card, is a type of payment card equipped with near-field communication (NFC) technology. Contactless cards are designed to make transactions faster and more convenient by allowing .Most debit and credit cards these days already have an NFC tag built-in. The aforementioned apps simply emulate these tags, with permission from the issuing bank or financial institution.
