MIFARE Classic® 4K

The MIFARE Classic® 4K contactless smart card is based on NXP MF1 IC S70, which is connected to a coil with a few turns and then embedded into plastic to form the passive contactless smart card. The communication layer (MIFARE RF Interface) complies with part 2 and 3 of the ISO/IEC14443A standard. The security layer sport the field proven CRYPTO1 stream cipher for secure date exchange of the MIFARE Classic® family. It is contactless transmission of data and energy and no battery is needed.

Being developed based on expanding the functions of MIFARE Classic® 1K, the MIFARE Classic® 4K increases memory size significantly. Therefore, it is the perfect solution for multi-application cards and allows more flexible and convenient to users.
