Description: The Mifare 1k contact less smart card is based on NXP MF1 IC S50, which is connected to a coil with a few turns and then embedded in plastic to form the passive contact less smart card. The communication layer (mifare RF Interface) complies with part 2 and 3 of the ISO/IEC1443A standard. It is contact less transmission of data and energy and no battery is needed. Mifare 1k is fundamentally used for storing memories, while a simple security mechanism divides the memories into segments. Therefore, it is ideal for high volume transactions in all different applications, such as transport ticketing, time attendance solutions, car parking, road-tolling etc. It is mainly used in closed systems as fixed value tickets (e.g. weekly/monthly travel passes). Features: Model: Mifare 1K Frequency: 13.56MHz Protocol: ISO14443A EEPROM Size: 1024 Byte Material: PVC Temperature: -20° - +50° Dimension: 85.6 × 54 × 0.86 (mm) Compatible with our RFID R/W Module SL025M
