NXP Semiconductors has developed the MIFARE MF1S503x to be used in a contactless smart card according to ISO/IEC 14443 Type A.
The MIFARE MF1S503x IC is used in applications like public transport ticketing and can also be used for various other applications.
Anti-collision
An intelligent anti-collision function allows to operate more than one card in the field simultaneously. The anticollision algorithm selects each card individually and ensures that the execution of a transaction with a selected card is performed correctly without interference from another card in the field.
Simple integration and user convenience
The MF1S503x is designed for simple integration and user convenience which allows complete ticketing transactions to be handled in less than 100 ms.
