Most credit card verification systems only verify whether the card is valid and not if the presenter is the authorized cardholder. MasterCard intends to address that with its newly introduced card with a built-in fingerprint sensor.
This new MasterCard gives customers the option of using a single digit rather than a PIN. It’s a very impressive development, particularly since it works with existing chip readers.

The card gives new meaning to the title “cardholder” as the customer must physically hold the card during the transaction. There’s a fingerprint sensor on the face of the card that syphons enough power from the chip reader to read and validate a fingerprint. If dirt, sweat or other factors prevent validation, the transaction can be completed with a PIN.
