What is the EM card? EM card is one of RFID cards with an EM chip. Common EM card include EM4100 card, EM4200 card, EM4033 card, EM4023 card, EM4305, etc. EM4200 card that we recommend is a classical LF RFID card, working on 125KHZ. It has the characteristic of low consumption, low cost, higher reading range performances, and good compatibility. EM4200 125KHZ RFID Card is compatible with EM4100/4102 and EM4005/4105 communication protocols.


EM4200 card usually is made of PVC or PET, and the EM4200 chip determines the performance of the card. EM4200 chip is a CMOS integrated circuit intended for use in electronic Read Only RF transponders. It can replace EM4100/4102 chip and EM4005/4105 chip directly. Here are the features:
  • Full compatible with EM4100/4102 and EM4005/4105 communication protocols.
  • 28-bit laser programmed ROM (64 and 96-bit option available)
  • Several options of data rate and data encoding:

                 ➤ Manchester 32 and 64 RF clocks per bit
                 ➤ Biphase 32 and 64 RF clocks per bit
                 ➤ PSK 16 RF clocks per bit (subcarrier RF/2)
                 ➤ FSK2 50RF clocks per bit

  • Several resonant capacitor integrated on-chip(0pF, 75pF or 250pF mask option)
  • 100 to 150 kHz frequency range
  • On-chip rectifier and voltage limiter
  • No external supply buffer capacitor needed
  • -40°C to +85°C temperature range)
  • Very low power consumption and High performances
