Forum type 2 tag Mifare Ultralight NFC card

1.1 Key applications

Limited chip card use tickets for public transport
Limited use tickets for event ticketing

1.2 Contactless energy and data transfer
MF0ICU1 is connected to a coil with a few turns. The MF0ICU1 fits the TFC.0 (Edmondson) and TFC.1 (ISO) ticket formats as defined in BS EN753-2.
TFC.1 format tickets are supported by the MF0ICU10 chip which features a 17 pF on-chip resonance capacitor.
The smaller TFC.0 format tickets are supported by the MF0ICU11 chip which features a 50 pF on-chip resonance capacitor.
1.3 Anticollision
An intelligent anticollision function enables simultaneous multicard operation. The anticollision algorithm individually selects each card and ensures correct execution of a transaction with the selected card without data corruption from other cards in the field.
1.3.1 Cascaded Unique IDentification (UID)
The anticollision function is based on an IC individual serial number called Unique Identification (UID) for each IC. The UID of the MF0ICU1 comprises 7 bytes and supports ISO/IEC 14443-3 cascade level 2.
1.4 Security

7-byte UID in accordance with ISO/IEC 14443-3 for each device
32-bit user definable One-Time Programmable (OTP) area
Field programmable read-only locking function per page

1.5 Delivery options
MF0ICU1 can be delivered in packaged or wafer form. Refer to delivery type description for more information.

Factors mifare ultralight affecting card read distance is more, by using different protocols, different antenna design, the surrounding environment (mostly metals) and different CARDS, etc., will affect the actual card read distance. Our desktop card read distance, speaking, reading and writing device in the 0 to 8 cm. We not excessive pursuit of reading card distance, but more emphasis on the stability of the card reader, card the critical region of the magnetic field to read our products don't reading CARDS, but in the area of magnetic energy to make the most read card, in order to increase its stability.
