GS1 DataBar Expanded

GS1 DataBar Expanded barcode in PHP: element string input, capacity, code examples and SVG output

- Nicola Asuni

The only member of the DataBar family that carries more than a GTIN. It takes the same bracketed element string as GS1-128, compacts it, and draws it in 4 to 22 symbol characters.

Capacity is counted in bits rather than characters, up to 252 of them, because the compaction depends on what the Application Identifiers are: a price field costs less than free text.
