Samsung is currently teasing the upcoming S22 series, which it will unveil in the next Galaxy Unpacked event. Amidst all this preparation, Samsung has announced the world’s first “all-in-one” fingerprint security chip for payment cards. With the new S3B512C security IC chip, Samsung is looking to make card transactions both faster and safer.

Samsung S3B512C All-in-one Security IC Chip:

S3B512C is the first “all-in-one” security IC (Integrated Circuit) chip from Samsung, designed in collaboration with Mastercard. This new chip combines fingerprint sensor, Secure Element (SE), and Secure Processor in one common IC.

The fusion of three different components on a single S3B512C security chip removes the need for individual ICs and the manufacturing cost associated with each. Samsung also believes that it will help cards manufacturers in optimizing and designing payment cards.

Potential Applications

Samsung S3B512C “all-in-one” security chip will add an extra layer of security to payment cards. However, it can act as an authentication mechanism for identity document cards. membership cards and even building accesses.

This will open the way for cards manufacturers to replace PINs with fingerprint data. Similarly, these cards will offer more resistance to fraud as the owner’s biometric data is on the card itself.

Working Mechanism

Here, the fingerprint scanner will read the user’s biometrics data. It is then stored on the Secure Element (SE), which protects it from being tampered with. SE is also responsible for the authentication of encrypted data via a proprietary algorithm.

Then there is the Secure Processor, which analyzes and processes fingerprint data on the sensor. S3B512C also has an anti-spoofing technology to prevent hackers from getting in using illegitimate methods.

Security Certifications

As for security, Samsung’s “all-in-one” S3B512C IC security chip has passed Mastercard’s latest Biometric Evaluation Plan Summary (BEPS) specifications for biometrics payment cards. In addition, it also has EMVCo and Common Criteria Evaluation Assurance Level (CC EAL) 6+ certifications.
