MIFARE Classic EV1


MIFARE Classic ICs started a revolution in the contactless smart card business back in 1994. Today, they’re still used in a variety of applications worldwide. The MIFARE Classic EV1 represents the highest evolution of the product family and succeeds in all previous versions. These solutions provide excellent ESD robustness for easy handling of the IC during inlay and card manufacturing and best-in-class RF performance for optimized transactions—allowing for more flexible antenna designs.
For security-relevant applications, customers should refer to our MIFARE DESFire and MIFARE Plus product families.

MIFARE Classic EV1 (1K - 4K)

NXP® has developed the MIFARE® MF1ICS50 to be used in a contactless smart card according to ISO/IEC 14443 Type-A.

The MIFARE MF1ICS50 IC is used in applications like public transport ticketing where major cities have adopted MIFARE as their e-ticketing solution of choice.

An intelligent anti-collision function allows operating 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 data corruption resulting from other cards in the field.

The MF1ICS50 is designed for simple integration and user convenience. Which could allow complete ticketing transactions to be handled in less than 100 ms. Thus, the MF1ICS50 card user is not forced to stop at the reader leading to high throughput at gates and reduced boarding times onto buses. The MIFARE product-based card may also remain in the wallet during the transaction, even if there are coins in it.
