Embedded NFC Reader Module UART Interface


  • NFC
  • Compact and easily embedded

The RC-S620/S is a compact NFC reader module.
Available with UART interface and suitable for incorporating into various devices, such as consumer devices, embedded system devices, and so on.

Main target devices : *PC *PC peripheral devices *AV devices *Access control readers *Loyalty point / membership card terminals


NFC functionality

Reader/writer function for ISO/IEC 14443 Type A / Type B cards and FeliCa cards.

Compact design with integrated antenna

The antenna and control parts are mounted on a single printed-circuit board with dimensions of 43 mm x 70 mm.
This design is less prone to the impact of the installation environment when embedded, and can therefore be embedded in various devices.

High-speed communication (424 kbps)

In addition to 212 Kbps, high-speed communication of 424 kbps is available to communicate with the mobile FeliCa IC chip or FeliCa cards with 424 kbps capability.

Application development environment

SDK for NFC <Reference Implementation> (optional) supporting FeliCa and ISO/IEC 14443 Type A / Type B communication is available as application software development tool for the host controller.
