Next-generation MCU for biometric System-on-Card and dCVV solutions

STMicroelectronics is enabling advanced security for contact and contactless payment cards, ID cards, and transport ticketing with its latest-generation ST31 secure microcontroller.

The ST31N600, based on ST’s 40nm eSTM technology, integrates circuitry for energy harvesting and additional connectivity used by biometric and dynamic card verification (dCVV) applications, enabling battery-free smartcards to provide enhanced user authentication in contactless and online transactions.

Based on the latest-generation Arm SecurCore architecture, the ST31N600 meets EMV ISO 7816, ISO 14443, and ISO 18092 standards for contact and contactless cards and enables designers to securely connect various types of peripherals to introduce value-added card features.

“The ST31N600 is the starting point for great advances in smartcards, with its strong security and features that enable easy-to-use and innovative authentication mechanisms for payments,” said Laurent Degauque, Marketing Director, Secure Microcontroller Division, STMicroelectronics.

STPay-Topaz-Bio is a ready-to-use payment solution that adds the security of biometric cardholder authentication to the convenience of contactless transactions. This Biometric System-on-Card (BSoC) solution is based on ST31N600 with an ultra-low-power STM32L4 microcontroller, both embedded in an EMV (Eurocard Mastercard Visa) module. The ST31N600 hosts payment applications, biometric-template matching and energy harvesting to power the system.

The same ST31N600 product is also suitable for ecommerce payment based on dCVV technology that provides a dynamic code refresh on each EMV transaction without needing an external battery or clock timer.

  • STMicroelectronics will be showcasing this device at Trustech 2021, in Paris.
