Dual-interface MCU selected for smartcard payment solution

According to the STMicroelectronics, the ST31G480 is the only device available today that can automatically detect and handle different types of radio-frequency communication used by the card readers. This enables Sony and other OEMs to develop and deploy contactless multi-application payment cards that can operate across different standards, infrastructures and geographies.

Sony’s smartcard payment solution will be the first in Japan to combine both the latest VISA/MasterCard/JCB dual-interface payment schemes and the FeliCa-based payment applications in a single chip. In addition to multi-payment functionality, the ST chip-card technology ensures stable transaction speeds, robustness and ease of use.

"The unique advantages of ST's secure MCU have enabled us to integrate, in a highly secure and cost-effective manner, standard payment and FeliCa-based applications in a single chip," commented Kazuyuki Sakamoto, Senior General Manager, FeliCa Business Division, Sony. "This technological advancement will increase convenience for Japanese consumers by expanding the opportunities to use their payment cards in many different settings and situations with unprecedented ease."

"Our co-operation with Sony further strengthens ST's position in the digital security arena, facilitating the deployment of secure and convenient contactless solutions to tech-savvy markets like Japan and Asia," commented Marie-France Florentin, General Manager, Secure Microcontroller Division, STMicroelectronics.
