GS1 Databar / RSS 14 Barcodes in LEADTOOLS (original) (raw)
GS1 Databar, formerly known as Reduced Space Symbology (RSS), is a large family of barcodes that encode a GTIN-12 or GTIN-13 data structure within a 14-digit barcode. The various GS1 Databar symbols have specific features that allow them to be read by different types of scanners. They are used in a variety of industries, including retail point-of-sale applications, inventory tracking, and healthcare.
Symbols Intended for Retail Point-of-Sale Scanning
Symbols that are not Intended for Retail Point-of-Sale Scanning
GS1 Databar Truncated (Databar-14 Truncated)
GS1 Databar Limited
GS1 Databar Stacked
GS1 Databar Omni-directional
GS1 Databar Omni-directional barcodes encode the full 14-digit EAN.UCC item identification in a linear symbol. They can be scanned omni-directionally by suitably programmed point-of-sale scanners.
GS1 Databar Omni-directional was developed to increase the number of unique codes, and to meet the needs of encoding more information in a smaller space.
GS1 Databar Truncated has the same data characteristics as the GS1 Databar barcode, except the bar height is set to the GS1 Databar standard of 13 times the X dimension.
GS1 Databar Truncated is designed to be scanned by wands, linear 2D imagers and handheld lasers. It cannot be scanned efficiently by omni-directional scanners.
GS1 Databar Stacked is a variation of the GS1 Databar symbology that is stacked in two rows. It is used when the normal symbol would be too wide for the application.
GS1 Databar Stacked is used for small item marking applications and it is designed to be scanned by wands, linear 2D imagers, and hand-held lasers. It cannot be scanned efficiently by omni-directional scanners.
The Omni-directional version of GS1 Databar Stacked can be scanned omni-directionally. This symbology does not allow for human-readable text with the barcode.
The data being encoded is separated to create a split-level barcode. The height of each row is ascertained from the bar's height property of the control. The barcode contains a separator pattern, containing no data, which has a height equal to 3 times the X dimension.
