RFID Module (LF-125KHz)

An LF RFID reader module (125KHz) is designed to communicate with RFID tags operating at 125KHz. It is widely used in access control, attendance management, and electronic billing systems.

1. Communication Interface

Supports TCP/IP, USB, BLE, WiFi, I2C, UART, Wiegand, RS-232, RS-485, enabling connection with computers, controllers, or network servers.

2. Communication Protocols

Compliant with ISO 11784 / ISO 11785 standards for reliable tag-reader communication.

3. Features

• Strong penetration through water, organic tissue, and wood
• Energy saving, stable reading in short-range environments
• Limited data storage and low transmission rate, suitable for low-speed, close-range identification

4. Antenna Function

Requires an antenna to transmit and receive RF signals; external antenna design affects performance and read distance.

5. Applications

Mainly used in access control, employee attendance systems, and electronic ticketing, where close-range and low data volume identification is sufficient.
