MIFARE 1 S50 is a serial of non-contacting smart card that meets the standard of ISO/IEC 14443A. The communication layer (MIFARE RF interface) meets part2 and 3 of the ISO/IEC 14443A standard. The security layer supports CRYPTO1 data stream encryption of domain authentication.

MIFARE RF Interface (ISO/IEC 14443 A)
• Non-Contacting data transmission and supplied power(no battery needed)
• Working distance: no more than 100mm (depends on the antenna dimension)
• Working frequency: 13.56 MHz
• High data transmission speed: 106 k bit/s
• Data integrity protection: 16 bit CRC, odd-even check, encoding and counting by bit.
• Anti-conflict
• Data transmission and processing time: < 100 ms (including backup and management time)

EEPROM
• 1 k byte (16 zones, 4 sections per zone, 16 bytes per section)
• User definable reading/writing condition for memory block
• Long time data storage: 10 years
• 100,000 writing times

Security
• Triple accreditation(ISO/IEC DIS9798-2)
• Attack protective radio-frequency channel data encryption
• Two security keys (support multiple security levels) for each section
• Only one serial No. for one card
• Transmission security key to protect the access right of EEPROM during the transmission
