Contactless energy and data transfer

In the MIFARE® system, the MF0ULx1 is connected to a coil with several turns. MF0ULx1 complies with TFC.0 (Edmondson) and TFC.1 (ISO) ticket formats.

The MF0ULx1 chip, which contains a 17 pF on-chip resonant capacitor, supports both TFC.1 and TFC.0 ticket formats.

Anti-collision

The intelligent anti-collision function allows more than one card to be in use at the same time. The anti-collision algorithm selects each card individually. It ensures that the transaction with the selected card is carried out correctly without interference from other cards in use.

Easy integration and user convenience

The MF0ULx1 is designed for easy integration and user convenience, enabling complete ticketing transactions to be processed in less than 35 ms.
