●Overview
●NXP 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
