· Logical access control · Online payment · ID authentication · Loyalty service


Optimized for PC, tablet, and other consumer electronic devices

The RC-S660/U module is suitable for incorporating into any laptop PC. While maintaining communication performance comparable to that of conventional products, the form factor of the product is reduced by about 40 percent, enabling its incorporation into more versatile compact devices.

Available for various contactless IC cards

The module is read/write compatible with FeliCa cards, FeliCa-compatible devices, ISO/IEC 14443 Type A / Type B and ISO/IEC 15693 cards and tags.

Conforms to PC/SC 2.0 specification

A PC/SC API is provided to access FeliCa cards, ISO/IEC 14443 Type A / Type B and ISO/IEC 15693 cards and tags.

CCID protocol compliant

CCID protocol allows PC/SC access on many platforms that support smart cards.

Application Development Environments

The following Software Development Kit (SDK) lineup supports the development of application software for various operating systems to control the reader:

SDK for NFC Lite for Windows OS (optional)

Supports application development for ISO/IEC 14443 Type A / Type B and ISO/IEC 15693 cards and tags, as well as FeliCa cards / FeliCa-compatible devices.

  • FeliCa Library is API-compatible with applications for RC-S600/620/632/634.
  • PC/SC applications have API-compatibility with RC-S632/634 applications.

SDK for NFC <Reference Implementation> for embedded systems (optional)

For other widely-adopted operating systems, such as Linux, reference source code with transplantable C language is provided to develop applications for ISO/IEC 14443 Type A / Type B and ISO/IEC 15693 cards and tags, as well as FeliCa cards and FeliCa-compatible devices.
