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.
