Specification :

The Mifare 4k contactless smart card is based on NXP MF1 IC S70, which is connected to a coil with a few turns and then embedded in plastic to form the passive contactless smart card. The communication layer (mifare RF Interface) complies with part 2 and 3 of the ISO/IEC1443A 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 1k, the Mifare 4k increases memory size significantly. Therefore, it is the perfect solution for multi-application cards£¬and allows the users to be more flexible and conveniently.
