SmartMetric Inc., maker of a biometric credit cards, has introduced its fingerprint scan credit card that uses a built-in fingerprint scanner to verify the identity of the cardholder when they make a payment, according to a press release.

The technology is designed to enhance the security and convenience of credit card transactions, especially for contactless payments as well as standard contact payments and ATM transactions.

Unlike PINs, fingerprint data is encrypted and is only stored in the card, bypassing the need for a central database connected to the internet, protecting a card user's sensitive data from hackers. Additionally, the technology safeguards against duplicated 2D and rubber fingerprints because it requires electrical capacitive sensing.

In addition, the card has an inbuilt hardware based live fingerprint detection. A user does not need to enter or remember a PIN number.

The cards are compatible with existing point-of-sale terminals that accept chip or contactless payments, so merchants don't need to invest in new equipment or software to accept them.

The card, which has its own internal rechargeable power, scans the user's finger prior to the card being inserted into a credit card reader. Therefore, the card is able to be used at all existing and types of credit card readers.

The card works at all card readers such as ATMs, parking ticket machines, transit ticket machines and restaurant and retail locations where the employee touches the sensor which turns on the card for up to eight minutes to process the card.
