Biometric card reference design from Infineon and NEXT Biometrics

Infineon Technologies and NEXT Biometrics have joined together to develop a reference design for biometric payment cards. The reference platform is said to include all necessary elements to develop and manufacture a smart card with a fingerprint sensor and help card makers to simplify their production processes and to shorten time-to-market for their offerings.

The use of biometrics for second factor authentication is the next big thing in payment card innovation following signatures, embossing, magnetic stripe and secure chip technologies. Instead of entering a PIN or showing an ID, the card holder authenticates by using a fingerprint sensor embedded on the card. The fingerprint information is stored on the card’s secure element and not shared with any third party, thereby protecting the user’s privacy.

According to the two companies, fingerprint authentication is faster and easier than standard PIN-based EMV* transactions. It will also further reduce fraud, especially when multifunctional cards are deployed for personal social security payments.

The biometric card reference design features a biometric module, a secure element, an operating system with biometric and payment applets, as well as a recommended and proven pre-lamination and lamination method for manufacturing the card. This complete system solution is designed to enable secure biometric smart card payment with significantly reduced false rejection rates to below one percent. The false rejection rate is a convenience feature that measures how often the fingerprint of the authorised user is reliably recognised and not incorrectly rejected.
