The technology behind the new tap-and-go cards sends data wirelessly to a nearby terminal, completing purchases with near-field communication, or NFC. The banks will virtualize the card with security measures inside the app, and therefore to make a payment, one needs to activate the application and bring the phone close to POS terminals.
