- At night, use the cable to charge the barcode reader. Plug the mini-USB end to the back of the reader and the other end to the computer.
Wired barcode reader
- Plug the USB side of the cable to the computer and the other end to the back of the reader.

Testing and troubleshooting
- To test the reader, click on any text field of GEM-CAR,
- Or open the "Notepad" application
- Scan the barcode of a product and see if the data is transferred to the computer
{fa-warning} If you hear a beep after while scanning the barcode and nothing is transferred to the computer:
- For a wired reader, try plugging the reader into another USB port on the computer,
- For a wireless reader, make sure you plugged in the USB stick to the computer. If it's already plugged in, try another USB port on the computer
When a new device is detected, you should usually see that window, unless you have a super-fast computer to the point that this process completed too fast.

You can also check your "Devices and Printers" in the "Control Panel" to see if you see a new device. Or if you are not sure what you are looking for, unplug and re-plug the device, while keeping an eye on the window, and see if there is a change with each action.
