MasterCard today unveiled a
biometric chip - and - pin credit card featuring a built - in fingerprint sensor that takes cues from mobile payment
systems such as Apple Pay.The card can be used to make purchases like any other, except rather than
keying in a PIN number, card holders can choose to place their finger over the square sensor to approve the transaction.Alternatively, users can take a two - tier authentication approach and use both their PIN and fingerprint to approve the purchase.
