The character set and code described in American National Standard Code for Information Interchange, ANSI X3.4-1977. Each ASCII character is encoded with seven bits.

EAN is designed by the International Article Numbering Association (EAN) in Europe. It is an extension to UPC-A to include the country information. EAN-13 encodes 12 digits of numeric data along with a trailing check digit, for a total of 13 digits of barcode data.

A character other than a 7-bit ASCII character. An extended character is a 1-byte code point with the eighth bit set (ordinal 128 through 255).

A family of bar code symbols, including GS1 DataBar-14, GS1 DataBar Limited, GS1 DataBar Expanded, and GS1 DataBar-14 Stacked. Any member of the GS1 DataBar family can be printed as a stand-alone linear symbol or as a composite symbol with an accompanying 2D Composite Component printed directly above the GS1 DataBar linear component. Formerly known as Reduced Space Symbology (RSS).

A bar code symbol that encodes an GTIN-14 Identification Number plus supplementary AI Element Strings, such as weight and “best before” date, in a linear symbol that can be scanned omnidirectionally by suitably programmed Point-of-Sale scanners.

A bar code symbol that is a variation of the GS1 DataBar Expanded Bar Code Symbol that is stacked in multiple rows and is used when the normal symbol would be too wide for the application.

A bar code symbol that encodes an GTIN-14 Identification Number with Indicators of zero or one in a linear symbol; for use on small items that will not be scanned at the Point-of-Sale.

A truncated version of GS1 DataBar-14. The height is 10X. Used for small packaging and not fit for Point-of-Sale scanners.

A bar code symbol that is a variation of the GS1 DataBar-14 Symbology that is stacked in two rows and is used when the normal symbol would be too wide for the application. It comes in two versions: a truncated version used for small item marking applications and a taller omni-directional version that is designed to be read by omni-directional scanners. GS1 DataBar Expanded can also be printed in multiple rows as a stacked symbol.

Acronym for Global Trade Item Number. A 14-digit number that uniquely identifies a trade item.

Acronym for graphical user interface. A program interface that takes advantage of the computer's graphics capabilities to make the program easier to use.

Acronym for Printer Control Language, the page description language (PDL) developed by Hewlett Packard and used in many of their laser and ink-jet printers.

The UPC-A barcode is the most common and well-known symbology in North America. UPC-A encodes 11 digits of numeric data along with a trailing check digit, for a total of 12 digits of barcode data.
