NXP Semiconductors has developed the MIFARE Classic MF1S50 to be used in a contactless smart card according to ISO/IEC 14443 Type A.
The proximity card MIFARE Classic 1K MF1S50 IC is used in applications like public transport ticketing and can also be used for various other applications.
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 interference from another card in the field.
Simple integration and user convenience
The MF1S50 is designed for simple integration and user convenience which allows complete ticketing transactions to be handled in less than 100 ms.
Security
• Manufacturer programmed 7-byte UID or 4-byte NUID identifier for each device
• Random ID support
• Mutual three pass authentication (ISO/IEC DIS 9798-2)
• Individual set of two keys per sector to support multi-application with key hierarchy
