There are barcode scanning libraries that specialise in scanning dozens or hundreds of barcodes in a single frame.
These are typically used to mass-import your competitors prices just by walking through the shop with a camera mounted on your shoulder. Or phone in a shirt pocket with the camera facing forward.
There’s a few white-label companies that offer these apps. Many of the barcode companies offer their own version of this app. They’re not usually available on the AppStores.
The reason for this is that each competitor requires slight customisation (font, price location relative to each barcode, etc) to get the best results.
- Ntrails 1y agoI thought barcodes were effectively just "guids" that you could use for a lookup table or whatever to get pricing etc. Knowing what the product _is_ wouldn't tell you what the price is - you'd need the table. How does it actually work?
- slau 1y agoYou're right, barcodes are just unique IDs individually identifying producers and products. However, as I wrote, the vendors of these systems provide customisation services to improve the OCR of the price relative to the barcode. Location, font, etc. Even the name can be imported, and in some cases shelf space per product, thus stock estimates, etc.
