Today tested the barcode reader. It starts out of the box in keyboard mode. That's convenient because no drivers needs to be installed! Additionally I did some testing of barcodes. 1D, 2D and even PDF-417 worked like a charm (even from the computer screen). It is light so easy to keep in your hand and very well build. Cable is flexible and long enough. So very good device! Impressed for the price and recommend it! Really nice to have the option of Keyboard or COM port! For the constructor; Would be nice to have the option to scan a barcode to control the beeping, sound or no sound when a valid barcode is scanned.
