EM4102 / EM4200 RFID Cards – 125 kHz Passive Identification

EM4102 and EM4200 RFID cards operate at 125 kHz and are widely used in access control solutions, animal tracking, and time attendance systems.

These chips work in read-only mode with a unique 64-bit identifier (UID). The EM4200 is an enhanced version of the EM4102, offering full compatibility with existing infrastructures, but with improved performance in terms of range and data integrity.

With Manchester and Biphase encoding, they are compatible with standard 125 kHz EM readers. Manufactured by EM Microelectronic, they offer a reliable solution for automatic contactless identification.

Ideal for companies requiring durable, cost-effective cards with high read rates in demanding environments.
