FeliCa SAM for readers


  • AES supported
  • High security
  • FeliCa Lite-S support

RC-S500/SO2 is the FeliCa™ SAM for readers that support AES and DES encryption systems. This product enables various terminals to utilize FeliCa security functions for a wide range of applications.
In addition, RC-S500/SO2 supports FeliCa Lite-S card.


Offering secure access functionality to FeliCa cards using AES/DES encryption

RC-S500/SO2 product is a Secure Application Module (FeliCa SAM) for readers that provide the necessary functionality for secure access to FeliCa Standard cards with AES/DES encryption systems. To develop a FeliCa secure reader system, simply insert this product into the SIM card slot of the reader terminal.

High level of security / Fast data communication

The security IC chip mounted in this product has obtained Common Criteria (ISO/IEC 15408) EAL5+ certification. By storing the encryption keys and security algorithm in the IC chip, it is possible to create a high-security system with this product.
Furthermore, this product can communicate with a reader, in which this product is inserted, at a maximum data transfer speed of 1.25 Mbps*, suitable for systems that require fast processing.

* With the input clock running at 10 MHz.

FeliCa Lite-S support

RC-S500/SO2 supports authentication between FeliCa Lite-S card and the reader, and read/write with MAC*. In addition, it supports the FeliCa Lite-S Diversified Card Key standard generation algorithm for authentication by using an individualized Card Key.

* MAC: Message Authentication Code
