The MIFARE Classic® 1K contactless smart card is based on NXP MF1 IC S50, 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. It is contactless transmission of data and energy and no battery is needed.
MIFARE Classic® 1K is fundamentally used for storing memories, while a simple security mechanism divides the memories into segments. Therefore, it is ideal for high volume transactions in all different applications, such as transport ticketing, time attendance solutions, car parking, road-tolling etc. It is mainly used in closed systems as fixed value tickets (e.g. weekly/monthly travel passes).
