ST, G&D and FitPay have used ST’s security chip to jointly create the first secure hardware and software solution that is pre-approved for use by device manufacturers with the aim to develop integrated tokenized payments from Mastercard or Visa.
This effort reduces the barriers to implementing card payments on mobile devices and enables wearable-device OEMs to concentrate on product development.
A secure operating system (G&D), payment application management software (FitPay), and hardware components needed to support a mobile payment application are included and fully integrated around ST’s ST54E security chip (embedded Secure Element, eSE) that handles cryptographic processing and tamper-proofing.
Alongside the ST54E, the reference design contains the STS39230 NFC booster that supports contactless connection to the payment terminal and allows a small-size antenna, an LIS2DS12 MEMS accelerometer that enables gesture-activated payment, Bluetooth Smart ICs, a USB battery charger, and an energy-saving microcontroller from ST’s ultra-low-power STM32L4 line.
“As the market for payment-enabled wearables grows, manufacturers need easy ways to bring secure transactions and connectivity to their devices,” said Avin Arumugam, SVP, Internet of Things (IoT), Visa Inc. “The solution ST and its partners are offering is a critical step in bringing contactless Visa payments to a whole new generation of IoT devices.”
