Flexible RFID and proximity solutions


The COMPACT module is an extremely small-sized contactless module, especially developed for integration in third parties terminals.
The COMPACT module is available for both 125 kHz ( EM or HITAG ) and 13,56 MHz ( MIFARE or Legic ) and can be supplied with a wide variety of data interfaces, such as Wiegand, Clock&Data and RS232 TTL.
Available versions:

  • COMPACT-EM : a 125 KHz module for EM4x02 transponders
  • COMPACT-HT : a 125 KHz module for Hitag transponders
  • COMPACT-MF : a 13,56 MHz module for MIFARE transponders
  • COMPACT-LG : a 13,56 MHz module for Legic transponders

All these module types can be supplied with a wide selection of different data interfaces, such as various Wiegand, Clock&Data and RS232 TTL outputs, or customer specific interfaces.
