MIFARE Ultralight Card (смарт-карты)

General description The MIFARE MF0ICU1 has been developed by NXP Semiconductors for use with Proximity Coupling Devices (PCD) in accordance with ISO/IEC 14443 A (see Ref. 1). It is intended for use with single trip tickets in public transportation networks, loyalty cards or day passes for events as a replacement for conventional ticketing solutions such as paper tickets, magnetic stripe tickets or coins. As the usage of contactless proximity smart cards becomes more and more common, transport and event operators are switching to completely contactless solutions. The introduction of the MIFARE Ultralight for limited use tickets will lead to a reduction of system installation and maintenance costs. Terminals will be less vulnerable to damage and mechanical failures caused by ticket jams. MF0ICU1 can easily be integrated into existing schemes and even standard paper ticket vending equipment can be upgraded. This solution for low cost tickets can help operators to reduce the circulation of cash within the system. The mechanical and electronical specifications of MIFARE Ultralight are tailored to meet the requirements of paper ticket manufacturers. 1.1 Key applications • Limited 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.
