Sony’s FeliCa Lite S NFC tag can be used as a plain memory tag like any other NFC tags. But in addition, it offers mutual authentication functions, protection of read and write access, and more.

These features can be used to implement secured services using a low-cost tag. While not offering as much security as traditional smart cards ( like the standard FeliCa card), the security functions of FeliCa Lite S allow to design applications that provide some level of security while keeping the complexity and costs down.
