RFID Reader LF40C THR is an easy-to-operate read/write device to transfer transponder data to a computer for users who want to replace barcodes with RFID. The RFID Reader LF40C THR is connected to the PC via a USB interface. The device is connected directly to the computer. The device with keyboard emulation can be connected to a running PC. The reader automatically detects the driver and subsequently starts installation.

The reading operation starts at the touch of a button. If identification was successful, the device confirms this by a signal and a flashing LED. The collected data are transferred to the PC via USB interface, and can be displayed and processed in any input field or text document.

The RFID reader is configured via the Set button. The individual settings can be changed at the touch of a button and can be visualized in ASCII or HEX format in a text document on the screen. If the device is used in combination with an emulated COM port, data transfer is carried out using an ASCII protocol.
