NXP Semiconductors developed the MIFARE Ultralight EV1 MF0ULx1 for use in a contactless smart ticket, smart card or token in combination with a Proximity Coupling Device (PCD). The MF0ULx1 is designed to work in an ISO/IEC 14443 Type A compliant environment (see [1]). The target applications include single trip or limited use tickets in public transportation networks, loyalty cards or day passes for events. The MF0ULx1 serves as a replacement for conventional ticketing solutions such as paper tickets, magnetic stripe tickets or coins. It is also a perfect ticketing counterpart to contactless card families such as MIFARE DESFire or MIFARE Plus.
The MIFARE Ultralight EV1 is succeeding the MIFARE Ultralight ticketing IC and is fully functional backwards compatible. Its enhanced feature and command set enable more efficient implementations and offer more flexibility in system designs.
The mechanical and electrical specifications of MIFARE Ultralight EV1 are tailored to meet the requirements of inlay and paper ticket manufacturers.
In this document the term „MIFARE Ultralight card“ refers to a MIFARE Ultralight IC- based contactless card.
1.1 Contactless energy and data transfer
In a contactless system, the MF0ULx1 is connected to a coil with a few turns. The MF0ULx1 fits the TFC.0 (Edmondson) and TFC.1 (ISO) ticket formats as defined in Ref. 8.
The MF0ULx1 chip, which is available with 17 pF or 50 pF on-chip resonance capacitor, supports both TFC.1 and TFC.0 ticket formats.
1.2 Anticollision
An intelligent anticollision function allows more than one card to operate in the field simultaneously. The anticollision algorithm selects each card individually. It ensures that the execution of a transaction with a selected card is performed correctly without interference from another card in the field.
1.3 Simple integration and user convenience
The MF0ULx1 is designed for simple integration and user convenience which allows complete ticketing transactions to be handled in less than 35 ms.
