how to use this prog? I navozhu camera at the bar code of the book, on the scanner bar codes (frame) long flashes then red then green, then blue, but nothing happens.
This means that a barcode scanner can not scan a barcode. Perhaps because of poloho lighting or for some other reasons. Once the code is scanned the program will search for the book.
