FeliCa SAM for reader


  • AES support
  • High security
  • High-speed communication
  • Compatible with current products

The RC-S500 product is the FeliCa™ SAM for FeliCa readers that support AES and DES encryption systems.
This product enables various terminals to utilize FeliCa security functions for a wide range of applications.


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


Support for the new-generation AES encryption standard

For encrypted communication between a card and a reader, as well as between RC-S500 and a reader, further enhanced security is realized using the AES encryption system in addition to the existing DES encryption system.

High level of security

The security IC chip mounted in this product has acquired 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.

Fast data communication

The RC-S500 product can communicate with a reader, in which this product is inserted, at a maximum data transfer speed of 1.25 Mbps*1, suitable for systems that require fast processing.

*1 With the input clock running at 10 MHz.

Compatibility with current products ensured

The RC-S500 product is compatible with RC-S251 (in terms of commands*2 and electrical characteristics) to facilitate transfer to systems that use AES cards.

*2 Not including control commands, such as initial settings, and so on.
