Compact Antenna Module

RC-S111 Flexible Printed Circuit Module

  • AES supported
  • Flexible material

RC-S111 is a flexible and thin FeliCa™ Standard compact antenna module. Embedding the module into a device enables the use of various services that require advanced securities and high-speed processing, such as e-money and access control. In addition, the characteristic of flexural tolerance together with the flexible printed circuit makes it possible to incorporate the module in products made of soft materials such as leather, textile, and so on.


Supports Advanced Encryption Standard (AES) algorithm

This product has the high-security FeliCa Standard IC chip supporting AES encryption algorithm. It is suitable for applications that demand high-speed processing and advanced security, such as e-money payment and access control. The IC chip embedded in this product is the world's first contactless IC card chip with embedded software to acquire EAL6+ certification in accordance with Common Criteria (ISO/IEC 15408), the international standard for evaluation criteria in IT security.

Compact and flexible material

With its downsized antenna and compact shape, the module can be incorporated in a broader range of products.
This product is made from a thin and flexible material, so it can be incorporated in products made from leather, textile (fabric), rubber, silicone, and so on. It can also be incorporated in curved products*1 such as wristbands and bangles.

*1 Curves with a flexible volume of 2.2 mm or smaller in a longitudinal direction (curvature radius R=35 mm or larger) are recommended to achieve the communication performance.
