EM-18 RFID Reader Module – Product Description

The EM-18 RFID Reader Module is a compact and reliable 125kHz RFID reader designed for contactless identification and access control applications. It can read EM4100-compatible RFID cards and tags and transmit the unique ID directly to microcontrollers such as Arduino, ESP32, Raspberry Pi, PIC, and AVR through a TTL UART interface. Its plug-and-play design, low power consumption, and fast response make it ideal for attendance systems, security projects, smart locks, and automation applications.
