Why is the bar code of a supermarket item a single digit from the bar code on the shelf
The country codes should be 13 bits, and the barcodes in the supermarket should be in theory the same as the goods, and special times,
It's possible that it was typed incorrectly.I hope my answer will help you.
Search for example: imported food, sometimes 8 or 12 bits, some supermarket checkout system cannot recognize, the supermarket will stick shop inside code!
What do you mean? Supermarket commodity bar code of goods shipped, the goods across the country have is this code, but the items on the shelves of the bar code was made for every supermarket, contains items of category varieties goods such as many specific meanings, each supermarket items barcode is not the same, the supermarket items of barcode and supermarket goods is out of the sample
