Features
Contactless Mifare® Interface
• Physical Interface and Anticollision compliant to ISO/IEC 14443-2 and -3, Type A
- Operating frequency 13.56 MHz; data rate 106 kbit/s
- Contactless transmission of data and supply energy
- Anticollision logic: Several cards may be operated in the field simultaneously
• Read and write distance up to 10 cm and more (influenced by external circuitry i.e. reader and
inlay design)
• Short transaction times: Typical ticketing transaction < 100 ms (including backup); transaction
possible when card is moving
1 Kbyte EEPROM
• Block organization of memory, 16 sectors with fixed 4 blocks of 16 bytes each
• EEPROM updating time per block less than 4 ms
• Endurance > 100.000 erase / write cycles / bit
• Data retention > 10 years2)
• User definable access condition for each memory block
Security Features
• Unique chip identification number
• Mutual three-pass authentication between card and reader
- 48-bit key length
- 2 keys per sector enabling key management
- Transport key at chip delivery
• Data encryption for RF channel
• Data integrity supported by several mechanisms:
- 16-bit CRC
