Mifare 1k Card also known as Mifare Classic
NXP has developed the MIFARE MF1ICS50 to be used in a contactless smart card according to ISO/IEC 14443 Type A.
The MIFARE MF1ICS50 IC is used in applications like public transport ticketing where major cities have adopted MIFARE as their e-ticketing solution of choice.
Applications
*Public transportation
*Access control
*Event ticketing
*Gaming & identity
Anticollision
An intelligent anticollision function allows to operate more than one card in the field simultaneously. The anticollision algorithm selects each card individually and ensures that the execution of a transaction with a selected card is performed correctly without data corruption resulting from other cards in the field.
Simple integration and user convenience
The MF1ICS50 is designed for simple integration and user convenience. Which could allow complete ticketing transactions to be handled in less than 100 ms. Thus, the MF1ICS50 card user is not forced to stop at the reader 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.
Security
Several security measures like mutual challenge and response authentication, data ciphering and message authentication checks support the protection of the system against various attack scenarios. The UID of the IC as a base of key diversification supports the security concept.
