1) Outline

MIFARE LIGHT card is a small-capacity cards,with total of 384bit, suitablefor a use of a card.

2) Key Indicators

  • Capacity of 384
  • Numerical calculation using 16-bit
  • 128-bit data area (if not purse can up to 192 documents)

一、Key Indicators

  • Capacity of 8K-bit EEPROM
  • Divided into 16 sectors, each sector for the four, each 16 bytes, to block the access unit
  • Each sector has a separate set of passwords and access control
  • Each card has a unique serial number for 32-bit
  • With anti-collision mechanism and supports multiple card operation


  • Capacity of 32K-bit EEPROM;
  • Each sector has a separate set of passwords and access control;
  • Each card has a unique serial number for 32-bit;
  • With anti-collision mechanism and supports multiple card operation;
  • No power, comes with antenna, includes encryption control logic and communication logic circuit;
  • Data retention period of 10 years, can be rewritten 100,000 times, time unlimited;
  • Operating frequency: 13.56MHZ;
  • Communication Rate: 106KBPS;
  • Reading and writing distance: 10mm or less (related to the reader).
  • How it works: The electrical part of card is componented only with one antenna and ASIC.
  • Antenna: The antenna of card is only a few winding coil group, it is suitable for packaging to IS0 card.
  • ASIC:The ASIC is componented with a high-speed card (106KB baud rate) of the RF interface, a control unit and a EEPROM .
