You can use a barcode scanner to scan your products when you put them into your inventory.

You can then search for a product, inside a repair, using the barcode scanner.

You might need to change the scanner settings, so it does not add the ENTER symbol after each scan.
This way, the scanner will only transform the barcode to text, and not press ENTER afterwards.
Some scanners do this by default.

This example is using this scanner.

If we would scan the second (lower) barcode, the scanner would stop adding the ENTER key.

If we would scan the first (upper) barcode, the scanner would start adding the Enter key again.
