The RC-S938 is a contactless IC module designed to embed into wristwatches or other devices and has the same functions as "FeliCa" card even in this tiny size. This module based wristwatch allows users to enjoy all kinds of services without having to dig cards or IDs out of their wallets and bags.
 |
- Small diameter (Outer : 26.5 mm).
- Doughnut-shaped for easy integration into a wristwatch.
- Functions equivalent to those of FeliCa cards (file system, encrypted communication with the Reader/Writer, etc.)
- We offer modules at different frequencies (12.80, 13.00, 13.56MHz) to match your manufacturing conditions.
