MIFARE 1K S50 Card is also called MIFARE 1K card or S50 card. Mifare 1k S50 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, pub­lic trans­porta­tion, access man­age­ment, elec­tron­ic toll col­lec­tion, car park­ing, school and cam­pus cards, employ­ee cards, loy­al­ty cards etc. It is main­ly used in closed sys­tems as fixed val­ue tick­ets (e.g. weekly/monthly trav­el pass­es).
