An RFID Low Frequency (LF) reader is a device designed to communicate with RFID tags operating at low frequencies, typically at frequencies 125KHz、134KHz. Here are some key points about LF RFID readers:

 1. Communication Interface:

LF RFID reader typically support various communication interfaces such as TCP/IP、USB、BLE、WiFi、I2C、UART、Wiegand、RS-232、RS-485. These interfaces allow the reader to communicate with external devices such as computers, microcontrollers, or network servers.

 2 .Read Range:

LF RFID typically has a shorter read range, depending on the specific reader and tag.

 3. Data Transmission:

The data transmission rate of LF RFID systems is relatively low compared to higher frequency systems, which can affect the speed of data transfer in applications requiring frequent reads or large amounts of data.

 4. Advantages:

For the Low Frequency, it is not susceptible to interference in environments with liquid or metal, and can penetrate liquids. Therefore, the Low Frequency has strong penetration ability, and little interference from the outside world.

 5. Applications:

When the operating frequency band is 125KHz, it is suitable for access control systems; when the operating frequency band is 134KHz, it is suitable for animal tracking, semiconductor wafer management and other applications.
