Yes David, As Andrew Ballantine suggested they are surely using camera technology for these mobile tags. My scanner is a cheaper one (LCD) not sure they are no scanner able to do that. Mmm, may be not because were we see black they "see" real pixels colors that our brain transforms in black. Nevermind I found some problem wit my scanner on POS either on Windows and Linux. I also created an option on Catalog/EditProduct to create a PDF with product barcode with a reasonnable size I will submit a patch. BTW why is the shipment barcode so large ?
