I already had some experience with this kind of Chinese readers and technical aspects do not scare me. Like the others, he is recognized as a USB keyboard, and sends "tape" so the scanned barcodes. There are way to configure it to communicate in RS232 (serial port) and also choose whether to send the "Enter" at the end of reading. To configure this, it comes with a booklet "notice" includes a series of scanned barcodes. We need to know a minimum what we do to remove the beep, switch modes or playback speed.
I still encountered a bug with the firmware which occasionally read the numbers wrong when configured in French keyboard (it returns the equivalent not capitalized on your keyboard, like for & 1). The best way to counter this is to configure the computer and the drive by US keyboard, which can be a hassle if you will also use your keyboard.
