Universal Product Code. The UniversalProduct Code (UPC) (redundantly: UPC code) is a barcodesymbology that is widely used in the United States, Canada, Europe,Australia, New Zealand, and other countries for tracking tradeitems in stores.
Thus, while the first three digits of the productbarcode may sometimes indicate where the product wasmanufactured, it will not always do so. For example,a barcode that has 690 as the first three digitsindicates that the barcode was assigned by the Chinese EANnumbering authority.

Types of Barcodes
- Interleaved 2 of 5. Commonly found in warehouse, distribution,and manufacturing, Code I 2 of 5 is a numeric-only barcode used toencode pairs of numbers.
- Universal Product Codes (UPC)
- International Article Number (EAN)
- PDF417.
- Data Matrix.
- Quick Response (QR) Codes.
UPC Codes Show Country Of Origin. One wayto help determine a products country of origin has beenfound, and it is all related to the barcode label or UPCcode. On any product, the prefix to the barcode, thoselittle black lines that the cashier scans, can reveal theanswer.

The Universal Product Code (UPC) barcode is usedin the retail industry. UPC-A consists of 12 numbers. UPC-Econsists of 12 numbers that are compressed into 8 numbers for smallpackages. The European Article Numbering System (EAN) is a supersetof U.P.C.
Using barcodes to enter products can bequicker and more accurate than manually typing in item codes.

IDAutomationalso offers a free Code 39 barcode font.
More specifically, the sensor in the barcodescanner detects the reflected light from the illumination system(the red light) and generates an analog signal that is sent to thedecoder. The decoder interprets that signal, validates thebarcode using the check digit, and converts it intotext.
Barcodes and barcode scanners. by ChrisWoodford. A barcode represents the line of numbers printedunderneath it with a pattern of black and white bars.Barcodes are designed for computers to read quickly byscanning red LED or laser light across them.
The QR code, similar to a barcode, is anexample of an information matrix. However a significantdifference in the two is that while a barcode onlyholds information nicely in the horizontal direction, a QRcan do so vertically as well. Compared to a barcode, it's nocompetition at all.
The nominal size of a UPC is 100% magnification factoror 1.469 inches wide (from the far left hand side number to the farright hand side number) by 1.02 inches tall (from the top of thebar code to the bottom of the human readable numbers).
Barcodes are applied to products as a means ofquick identification. They are used in retail stores as partof the purchase process, in warehouses to track inventory, and oninvoices to assist in accounting, among many otheruses.
A 101x101 QR code, with high level errorcorrection, can hold 3248 bits, or 406 bytes. Probably notenough for any meaningful SVG/XML data. A 177x177 grid, dependingon desired level of error correction, can store between 1273and 2953 bytes. Maybe enough to store somethingsmall.
The most visually recognizable, the UPC (UniversalProduct Code) is a linear 1D barcode made up of two parts:the barcode and the 12-digit UPC number. The first sixnumbers of the barcode is the manufacturer's identificationnumber. The next five digits represent the item'snumber.
