Albasca USB handheld scanner MK-1000 barcode scanner -WITH stator to 390mm reading distance - 270 scans / sec. 32bit fast, high-resolution, read the GS1 codes (Electronics)
Unwrapped, plugged into USB connector (driver installs itself), directed light beam on books, numbers migrate to a text file, text file conclusively lines sorted together with automatic deletion of duplicates (because the scanner is too fast for me),
