Mastercard has rolled out a credit card that has an integrated fingerprint scanner, making it easier to authenticate purchases at retail stores. The card stores two fingerprints, and features an embedded sensor that lets you authorize payments instead of having to sign or use a PIN.
To get started, you'll have to register your fingerprints at your bank, after which the information will be converted to a "encrypted digital template" that will be stored on the card. Mastercard's biometric cards are just as thin as existing credit cards, and will work with current chip-and-PIN readers. You'll be able to authenticate purchases by placing your finger on the integrated biometric sensor, and the cards don't have require any batteries as they source power from the payment terminals.
