Solution

The correct option is C Price on the shelf

Price on the shelf is not necessary when using bar codes in supermarkets.

It also contains a check digit, so that the computer can validate that the data has been read in correctly. The barcode does not contain price. The price is held in the database instead. This makes it easy to change if there are special offers or prices go up.

The Universal Product Code (UPC) is a barcode symbol that is widely used in the United States, Canada, United Kingdom, Australia, New Zealand, in Europe and other countries for tracking trade items in stores.
