Backers of new radio-tagged product codes, a kind of souped-up bar code, are heralding this as the week the technology finally moves off the drawing board and into the real world.

Unlike traditional bar codes, Radio Frequency Identification tags do not need to pass under a laser reader. They are already commonly used by drivers with “speed passes” at toll booths, by U.S. military quartermasters and by ranchers tracking livestock from “farm to fork.”

But the MIT lab developing the technology and sponsors such as Wal-Mart, Gillette and Procter & Gamble, are calling a symposium this week in Chicago the beginning of the next step: embedding the chips in shipping crates to help big companies save billions by tracking their products from factory to warehouse to storeroom.

For now, the focus is on helping businesses make sure there are enough products to fill the shelves but not so much as to clog up supply lines or waste away in warehouses. Using RFID to track individual products all the way to the checkout line is further down the road when costs come down.

“The symposium is intended to be a bit like a starting pistol for this new technology,” said Kevin Ashton, executive director of MIT’s AutoID Center. “It’s where we cross the line from research to reality.”

For some, however, RFID is moving a little too quickly.

The technology got a push this summer when Wal-Mart told its top 100 suppliers to deliver RFID-tagged products by Jan. 1, 2005. With nearly $700 million in sales per day in 2002, Wal-Mart had the clout to give orders, and the announcement sent suppliers scrambling to respond.

Some of those suppliers, like Procter & Gamble, were already enthusiastically pursuing RFID on their own. A new research report suggests others are feeling rushed to implement it.

They are also worried that if a common set of RFID standards fails to emerge, they will have to build a new system for every customer. And if standards do emerge, they worry they will be forced to share information with competitors.

“With every supplier, there are two camps,” said Kara Romanow, an analyst with AMR Research, whose report estimated companies would spend $2 billion trying to meet the Wal-Mart deadline. “There’s the camp that believes the end vision and has really bought into the hype. Then there are the people that are charged with implementing it that are scared.”

Some privacy advocates, who contend the technology will soon be used to track people and their personal information, are also worried that RFID is moving too fast.

Katherine Albrecht of the privacy group Caspian said consumer advocates should have been invited to the Chicago symposium to discuss their concerns.

“It’s such a once-sided conversation about the needs of businesses, with so little input from the citizens and consumers who are the major stakeholders in society,” she said.

Ashton, of the AutoID center, said that privacy advocates should be part of the debate and that as the technology develops, safeguards will be adopted: Any customers who end up with RFID technology in their hands will be notified, given the option of turning it off, and given control over how any information is used.

The 1,000 people attending the Electronic Product Code symposium are likely to have questions about privacy, as well as standards and the rush by the “Wal-Mart 100” to comply with the company’s mandate.

Bentonville, Ark.-based Wal-Mart has a long tradition of setting tough rules for its suppliers, but experts say this is the toughest directive yet, given the tight deadline and the novelty of the technology.

Experts say some companies are doing the minimum to comply, but others are investing heavily, figuring the technology will eventually cut their costs. After all, when Wal-Mart adopted bar codes in the 1980s and helped make the technology an everyday product, suppliers also eventually made good use of it.
