What is the EM4305 RFID Card?

EM4305 RFID Card,otherwise known as EM4305 proximity card is a kind of common 125KHZ RFID card made of PVC or PET. It is often used as an access card, you maybe have used it but unknown its name. What is the difference between the EM4305 card and the EM4200 card ? The big difference between them is that the EM4200 card can only read, while the EM4305 card can read and write.

EM4305 RFID Card features 32-bit Password read and write protection, low power consumption, 512 bit EEPROM, no external supply buffer capacitor needed, and compatible with the EM4469/4569 family, etc. And it is very cheap and often used in low-cost applications that require tracking and identification, such as access control in campus, community, library, parking plot, etc.


If you want to know the complete function of the EM4305 RFID card, you must learn the characteristic of the EM4305 chip that plays a core role in the EM4305 card. Here some central features, and you can download the EM4305 DataSheet.
