Samsung has unveiled a new kind of credit card. It combines fingerprint sensor, secure element and security processor in a single chip.

With such a card, the PIN code becomes obsolete, and transactions become easier for users.

Biometric payment card: an unprecedented security chip

During its announcement, Samsung unveiled what it claims is the cash industry’s first-ever all-in-one fingerprint (IC) security chip. This chip, named S3B512C, is composed of a fingerprint sensor that reads biometric information, stores, and then authenticates the data using a tamper-proof secure element (SE). This data is analyzed using the secure processor integrated into the chip.

Thanks to this technology, banks will be able to create biometric payment cards more easily. Fruit of the collaboration between Mastercard and Samsung, the chip has the potential to be democratized to make these new cards much more common than they already are.

The biometric payment card: flawless identification?

The solution offered by Samsung meets the latest Mastercard security indications, but also international security standards. These security pledges aim to “ protect high-value assets against significant risks “, according to the company.

This chip should allow “ faster and safer interactions when shopping “, according to Samsung. Indeed, biometric identification removes the need to type in your code on a keyboard. The risks associated with the theft or loss of his credit card will also be reduced, since the chip verifies the identity of the holder thanks to his unique fingerprint. Identification is done through a proprietary fingerprint authentication algorithm, with the help of the processor analyzing each unique feature of the fingerprint placed on the sensor.

Data encrypted with the tamper-proof OS is doubly secure with anti-spoofing technology. It allows the blocking of fraudulent methods, such as the use of artificial fingerprints.

First designed for the use of bank cards, this chip could also allow the identification of students or employees to access buildings, for example.
