I have close to 4000 products in my store. Some of my suppliers provide upc codes in a spreadsheet that I have already added to products through database entry. Some of my suppliers don't have a list of upc codes, so here is my question. I have products on my store shelf with a barcode label, I would like to be able to add the upc code for that product by scanning the barcode with my socket mobile scanner rather than typing in the 12 digits. Any help would be appreciated.
