2. Universal Product Code - Wikipedia

   en.wikipedia.org/wiki/Universal_Product_Code

   A UPC barcode. The Universal Product Code (UPC or UPC code) is a barcode symbology that is used worldwide for tracking trade items in stores.. The chosen symbology has bars (or spaces) of exactly 1, 2, 3, or 4 units wide each; each decimal digit to be encoded consists of two bars and two spaces chosen to have a total width of 7 units, in both an "even" and an "odd" parity form, which enables ...

   en.wikipedia.org/wiki/GS1

   In 1973, the Universal Product Code (UPC) was selected by this group as the first single standard for unique product identification. In 1974, the Uniform Code Council (UCC) was founded to administer the standard. [1] On 26 June 1974, a pack of Wrigley's chewing gum became the first ever product with a barcode to be scanned in a shop. [1] [3]

4. International Article Number - Wikipedia

   These barcodes only represent the digits 0–9, unlike some other barcode symbologies which can represent additional characters. The most commonly used EAN standard is the thirteen-digit EAN-13, a superset of the original 12-digit Universal Product Code (UPC-A) standard developed in 1970 by George J. Laurer. [1]

5. EAN-8 - Wikipedia

   en.wikipedia.org/wiki/EAN-8

   An example of an EAN-8 barcode. An EAN-8 is an EAN/UPC symbology barcode and is derived from the longer International Article Number (EAN-13) code. [1] It was introduced for use on small packages where an EAN-13 barcode would be too large; for example on cigarettes, pencils, and chewing gum packets.

7. Electronic Product Code - Wikipedia

   en.wikipedia.org/wiki/Electronic_Product_Code

   The EPC is designed as a flexible framework that can support many existing coding schemes, including many coding schemes currently in use with barcode technology. EPC identifiers currently support 7 identification keys from the GS1 system of identifiers, as well as a General Identifier and EPC identifiers that can be used for encoding supplies ...

8. Interleaved 2 of 5 - Wikipedia

   en.wikipedia.org/wiki/Interleaved_2_of_5

   Interleaved 2 of 5 (ITF) is a continuous two-width barcode symbology encoding digits. It is used commercially on 135 film, for ITF-14 barcodes, and on cartons of some products, while the products inside are labeled with UPC or EAN. ITF was created by David Allais, who also invented barcodes Code 39, Code 11, Code 93, and Code 49.

9. Code 39 - Wikipedia

   en.wikipedia.org/wiki/Code_39

   The barcode scheme does not contain a check digit (in contrast to—for instance—Code 128), but it can be considered self-checking on the grounds that a single erroneously interpreted bar cannot generate another valid character. Possibly the most serious drawback of Code 39 is its low data density: It requires more space to encode data in ...
