The GS1 DataBar barcode is also known as Reduced Space Symbology (RSS). GS1 DataBar is a 1D barcode. It is self-checking with a high data density. The GS1 DataBar family is designed as a successor to the older EAN/UPC formats.

It can hold the 14 digits of the GTIN (Global Trade Item Number) and is smaller than the UPC and EAN barcode symbols. It carries more data than the UPC or EAN barcodes and its small size makes it a good candidate for small items, like produce.

"GS1 DataBar enables GTIN identification for fresh variable measure and hard-to-mark products like loose produce, jewelry and cosmetics. Additionally, GS1 DataBar can carry GS1 Application Identifiers such as serial numbers, lot numbers, and expiration dates, creating solutions to support product authentication and traceability for fresh food products and couponing."
