FM11RF08S (short for RF08S) is a logic security IC which based on ISO/IEC 14443A for the proximity contactless applications. It has excellent compatibility with all kinds of readers, enhanced RF performance and higher reliability of EEPROM. Comparing with the old version chip RF08, RF08S's security and anti-crack ability have been enhanced by fixing the weak points in the realization of the algorithm without losing of the functional compatibility. The communication distance has also been enhanced keeping the merit of compatibility with all kinds of readers.
