Radio frequency identification trailblazer Wal-Mart has urged SMEs to adopt the technology, insisting that it is not only big business that stands to gain.
The US retailer, which already has more than 100 suppliers using RFID, told the EPCglobal conference that more suppliers were realising, "Hey, it works."
Simon Langford, manager of Wal-Mart's RFID strategy, said small companies were already contacting it to get involved as soon as possible.
"Big and small companies see an opportunity to get a competitive advantage," he said. "Smaller suppliers are more nimble and can make the most of RFID."
Langford said there were no plans yet for Asda, Wal-Mart's UK arm, to get involved in RFID.
