EM-18 RFID Reader Module

EM-18 RFID Reader Module – 125kHz RFID Reader with TTL Output

The EM-18 RFID Reader Module is a widely used RFID Reader Module operating at 125kHz, designed for fast and secure contactless data reading. With an integrated antenna and simple serial (TTL) output, this module allows easy integration with microcontrollers such as Arduino, Raspberry Pi, and other embedded systems.

Once powered with a 5V DC supply, the EM-18 reads RFID cards or tags within a 6–10 cm range and outputs a 9600 bps ASCII serial data stream containing the unique 64-bit ID. The module supports EM4001 / EM4100 RFID tags, ensuring stable and accurate identification.

Its compact size, low power consumption, and plug-and-play operation make the EM-18 RFID Reader Module a preferred choice for both commercial systems and hobbyist projects. If you are searching for a dependable RFID solution at the right RFID module price, this module offers excellent performance and value.
