Autumn 2006

Smaller barcodes are on the way. A new standard called Reduced Space Symbology, or RSS, is due to come into use worldwide at the start of 2010. The new codes are over 50 per cent smaller than the GS1 bar codes currently in wide use, yet will hold more information. The two types will continue to be used side by side for an indeterminate time after that.

GS1, the global standards body in this field, says the smaller codes will appeal to any users wanting to share more information about the product with trading partners; to reclaim space on packaging for design purposes; or to provide more consumer communication.

Unlike current GS1 codes, the new ones can carry serial numbers, lot numbers and expiry dates. The hope is that they will help support product authentication and traceability initiatives, product quality assurance, variable-measure product identification and coupon handling.

But are the codes needed when RFID can cope with all this data and more? Yes, according to Andrew Osborne, chief technical officer at GS1 UK. He says: "RSS is a simple solution for trading partners looking for advanced information sharing who cannot justify the investment in RFID yet."

The delay in implementation is to ensure that scanning equipment can cope with the new codes, and data systems are prepared for the extra data they may contain.
