What is a UPC barcode? And how does it work?
Universal Product Codes (also known as GTIN-12) appear as lines (bars) of varying widths representing the series of numbers commonly shown below the bars. Barcode scanners, as you will know them from your favorite retailers, read the bars and convert them back to the 12-digit UPC number that they represent. This number is then looked up within the retailer's inventory system to find the corresponding product name and price that you provided them with when you signed your agreement for them to carry your product. In short, the UPC is a 12-digit unique code for your product represented by scannable bars.
Camera based scanners
Camera based scanners are also very interesting and merit a closer exam. The technology is very fresh, and they are not very popular at this point, but they allow the average person to scan his or her own bar codes. Most favorite on newer smart phones, these scanners actually dissect a picture of a barcode and use software to decode the meaning of the code itself. For the 1st the right time, almost anyone can decode favorite bar code types such as ISBM and UPC wherever they are and can promptly determine information on mostly any product.
