Barcode Symbology:
Global Standards One (GS1). As the name suggests, the organization can be considered primarily as the standards organization managing the assignment of various numbering schemes upon which global commerce has come to rely.
There are two basic bar codes:
Single Line Bar Code: holds information nicely in the horizontal direction:
QR: Referred to as two-dimensional, because they carry information both vertically and horizontally.

| Code 39 | common barcode type used for various labels such as name badges, inventory and industrial applications. ... The checksum character is a type of MOD43 |
|---|---|

GS1-128 (formerly known as UCC/EAN-128) is a subset of Code 128 and is used extensively worldwide in shipping and packaging industries as a product identification code for the container and pallet levels in the supply chain. |
| GSI-128 (EAN 128) | Subset of Code 128 and is used extensively worldwide in shipping and packaging industries as a product identification code for the container and pallet levels in the supply chain. |
| UPCA | Universal Product Code. ... UPC (technically refers to UPC-A) consists of 12 numeric digits, that are uniquely assigned to each trade item. Along with the related EAN barcode, the UPC is the barcode mainly used for scanning of trade items at the point of sale, per GS1 specifications. |
