A. UPC
Explanation:
A UPC is an acronym for universal product code. UPC is typically used for the identification of a specific product and its manufacturer (vendor) through a unique code that is printed on the product.
Basically, a universal product code (UPC) comprises of two (2) main parts;
- A machine-readable barcode that contains sets of vertical black lines.
- A unique twelve (12) digit number placed beneath or adjacent to the machine-readable barcode.
The first six-digits of the UPC represents the manufacturer and is printed on all of its products while the next five-digits is the product's unique reference number (item number) and the last digit is typically known as a check digit, used for the verification of the authenticity of a UPC.
Generally, the universal product code are usually scanned with a barcode scanner and this makes it easier to identify a product, as well as its price.
