NXP® 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.
An intelligent anticollision function allows operating 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.
The MF1S70yyX/V1 is designed for simple integration and user convenience which allows complete ticketing transactions to be handled in less than 100 ms.
