MF1 IC S50
Functional specification
1.3 User Convenience
The Mifare system is designed for optimal user convenience. The high data transmission
rate for example allows complete ticketing transactions to be handled in less than 100 ms.
Thus, the Mifare‚ card user is not forced to stop at the RWD antenna leading to a high
throughput at gates and reduced boarding times onto busses. The Mifare card may also
remain in the wallet during the transaction, even if there are coins in it.
1.4 Security
Special emphasis has been placed on security against fraud. Mutual challenge and
response authentication, data ciphering and message authentication checks protect the
system from any kind of tampering and thus make it attractive for ticketing applications.
Serial numbers, which can not be altered, guarantee the uniqueness of each card.
1.5 Multi-application Functionality
The Mifare system offers real multi-application functionality comparable to the features of
a processor card. Two different keys for each sector support systems using key
hierarchies.
1.6 Delivery Options
• Die on wafer
• Bumped die on wafer
• Chip Card Module
• Flip Chip Package
