EM4450/4550 is very mature, simple and widely used RFID technology. The chip we embed in the card is original from EM Microelectronic.

The difference between EM4450 and EM4550 is that EM4550 are bumped and has megapads for the two coils. The chip contains 1 KBit of EEPROM which can be configured by the user, allowing a write inhibited area, a read protected area, and a read area output continuously at power on. The memory can be secured by using the 32 bit password for all write and read protected operations. The password can be updated, but never read. The fixed code serial number and device identification are laser programmed making every chip unique.It is widely used in ticketing,automotive immobilizer with rolling code,high security hands free access control,prepayment devices etc.
