What are 125 kHz USB RFID Readers? Where Are They Used?

125 kHz USB RFID readers are RFID devices operating in the low frequency (LF) band that connect to computers via USB. These readers easily scan RFID cards, key fobs, and tags operating at 125 kHz frequency and automatically transfer data to the computer system.

Key Features of 125 kHz RFID Technology

• Operating Frequency: 125 kHz (LF – Low Frequency)

• Reading Distance: Between 2 and 10 cm

• Data Transfer: Instant via USB

• Compatibility: Windows, Linux, and some Android systems

• Plug and Play: Can be used without additional software (keyboard emulation)

Usage Areas

1. Personnel and Student Tracking
   Automatic logging of entry and exit by scanning staff cards in schools and offices.

2. Access Control Systems
