In the MIFARE system, the MF0ICU2 is connected to a coil with a few turns. The MF0ICU2 fits for the TFC.0 (Edmonson) and TFC.1 ticket formats as defined in EN 753-2.
TFC.1 ticket formats are supported by the MF0xxU20 chip featuring an on-chip resonance capacitor of 16.9 pF.
The smaller TFC.0 tickets are supported by the MFxxU21 chip holding an on-chip resonance capacitor of 50 pF.
When the ticket is positioned in the proximity of the coupling device (PCD) antenna, the high speed RF communication interface allows the transmission of the data with a baud rate of 106 kbit/s.
