Overview
Semiconductors has developed the MIFARE Classic MF1S70yyX/V1 to be used in a contactless smart card according to ISO/IEC 14443 Type A.
The MIFARE Classic EV1 4K MF1S70yyX/V1 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 MF1S70yyX/V1 is designed for simple integration and user convenience which allows complete ticketing transactions to be handled in less than 100 ms.
### Security and privacy
* 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
### Delivery options
* 7-byte UID, 4-byte NUID
* Bumped die on sawn wafer
* MOA4 and MOA8 contactless module
