JT308 125KHz USB Proximity Sensor Smart RFID ID Card Reader

The JT308 125KHz USB Proximity Sensor is a desktop RFID ID card reader that plugs into a computer's USB port. When you hold a 125 kHz EM4100-compatible card or key tag near it, it reads the card number and types it into the active window just like a keyboard, so it works with spreadsheets, attendance software and web forms without installing a driver.
