1. General description
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 Ref. 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.
1.1 Contactless energy and data transfer
In a MIFARE 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 features a 17 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.
