ST MCU integrates energy harvesting and dCVV connectivity

ST has come up with an MCU which integrates circuitry for energy harvesting and thenadditional 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 for secure MCU, the ST31N600 meets EMV ISO 7816, ISO 14443, and ISO 18092 standards for contact and contactless cards and lets designers securely connect various types of peripherals to introduce value-added card features.

STPay-Topaz-Bio is a ready-to-use payment product that adds the security of biometric cardholder authentication to the speed and convenience of contactless transactions. This Biometric System-on-Card (BSoC) solution is based on ST31N600 with an ultra-low-power STM32L4 MCU, 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 ST31N600 is 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.
