1D barcode: DataBar Omnidirectional (RSS-14)
The DataBar Omnidirectional barcode is a versatile and widely used barcode symbology designed for retail point-of-sale (POS) applications.
Its design allows for omnidirectional scanning, meaning it can be read from any angle, which is particularly useful at busy retail checkouts.
This barcode can encode a 14-digit numeric data stream, including Global Trade Item Numbers (GTINs) in various formats such as GTIN-8, GTIN-12, GTIN-13, and GTIN-14.
If the encoded number is shorter than 14 digits, zeros are added to the left to reach the required length.
The structure of the DataBar Omnidirectional barcode is defined in ISO/IEC 24724 and consists of 46 bars and spaces across 96 modules. It includes two pairs of symbol characters, each flanked by finder patterns that contain check digits calculated using the modulo 79 algorithm for error correction. This ensures data integrity and accuracy during scanning.
The barcode's design is optimized for compactness without sacrificing data capacity, making it ideal for smaller items that cannot accommodate larger barcode types.
In addition to retail POS, the DataBar Omnidirectional barcode is also used for labeling fresh foods, where it can hold additional information such as batch numbers and expiry dates. This capability is particularly beneficial for inventory management, reducing food waste, and offering discounts on items nearing expiration.
The adoption of DataBar Omnidirectional barcodes in the retail sector has been driven by their ability to encode more information in a smaller space compared to traditional UPC and EAN barcodes, as well as their enhanced scanning reliability.
As the retail industry continues to evolve, the use of DataBar Omnidirectional barcodes is likely to expand, further integrating into systems for improved traceability, inventory management, and customer experience.
