Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If the price of an item changes, you will need to replace the bar code.
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Once a barcode is made, the price on it cannot be changed. You would use the same ISBN on the new barcode because the book itself hasn’t changed.

Detailed explanation-2: -Because QR codes represent data in two directions, horizontally and vertically, there are three distinct advantages of QR codes over barcodes. QR codes can store more information. They can access that information faster.

Detailed explanation-3: -Can barcode information be changed? If the seller owns the barcode they can change the description to remove other sellers from that listing. If it was a manufacturer’s own barcode then the seller wouldn’t be able to change the description on the item.

Detailed explanation-4: -No, barcodes are not unique to stores, unlike SKUs which are specific to an individual store. Barcodes are universal and used across many different stores.
