NXP^® Semiconductors has developed the MIFARE^®MF1S703x to be used in a contactless smart card according to ISO/IEC 14443 Type A.

The MIFARE MF1S703x IC is used in applications like public transport ticketing and can also be used for various other applications.

1.1 Anti-collision

An intelligent anti-collision function allows to operate more than one card in the field simultaneously. The anti-collision 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.

1.2 Simple integration and user convenience

The MF1S703x is designed for simple integration and user convenience which allows complete ticketing transactions to be handled in less than 100 ms.

1.3 Security

• Manufacturer programmed 4 byte Non-Unique IDentifier (NUID) for each device
• Mutual three pass authentication (ISO/IEC DIS 9798-2)
• Individual set of two keys per sector to support multi-application with key hierarchy

1.4 Delivery options

• Die on wafer, bumped die on wafer
• MOA4 contactless module
