FeliCa™ Lite-S product is a small-size contactless IC chip with streamlined security function and an optimized file system.
"FeliCa Lite-S" can be used for any NFC Forum Type 3 Tag solution, such as handover connection and smart poster, in combination with any NFC device.
Features
Mutual authentication utilizing MAC*1
"FeliCa Lite-S" has read-access control and write-access control functionality due to the use of MAC to prevent any unauthorized access. The function to generate a MAC on "FeliCa Lite-S" makes it possible to carry out streamlined mutual authentication between the product and the reader, supporting secure application development.
*1 MAC: Message Authentication Code
NFC Forum Type 3 Tag
"FeliCa Lite-S" supports Type 3 Tag operation, as defined by the NFC Forum. Therefore, the chip can communicate with standard NFC smartphones and readers. The user memory of 224 bytes is sufficient for most NFC-tag applications and usages.
Several access attributes on a simple file system
The chip uses a simple file structure that has no hierarchical structure. It supports the following access attributes for each user block separately.
- - Read Only Access
- - Read / Write Access
- - Read After Authentication
- - Write After Authentication
- - Write With MAC
Anti-tearing transaction function and data integrity-check function
"FeliCa Lite-S" has anti-tearing transaction functionality to prevent incomplete data update. Even if a data error occurs in the chip, there is CRC data check code for every data block (16 bytes), so the data error can be detected.
A software development kit, "SDK for NFC", is available
Software Development Kit “SDK for NFC” is available to develop applications for “FeliCa Lite-S” and Sony NFC readers.
