The MIFARE Class 4K contactless access 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 the ISO/IEC14443A standard. It is contactless transmission of data and energy and no battery is needed.

MIFARE interface platform consists of a few product lines, and the MIFARE 4k belongs to the MIFARE Classic family. The MIFARE 4k are fundamentally used for storing memories, yet a simple security mechanism divides the memories into segments. Therefore, this product family is ideal for high volume transactions like transport ticketing, time attendance solutions, car parking and loyalty programs.
