Product Name:QR2272
Brief:
The air interface of QR2272 chip complies with part 2 and 3 of the ISO/IEC 14443A standard, integrated with 128bits TEA encryption. The chip also contains 48bits random numbers generator. The chip adopts 3-pass authentication (ISO/IEC DIS 9798-2), and CRYPTO1 stream encryption in all data to prevent being intercepted. The 4-byte UID is programmed during fabrication and cannot be modified later, which is actually a very effective anti-clone approach. This UID number can be used to encrypt the data in the chip or to derive diversified keys per ticket.
