Bar code that tracks

Tiny Antennas to Keep Tabs on U.S. Drugs
The Food and Drug Administration and several major drug makers are expected to announce initiatives today that will put tiny radio antennas on the labels of millions of medicine bottles to combat counterfeiting and fraud. "It's basically a bar code that barks," said one expert, Robin Koh, director of applications research at the Auto-ID Labs of the Massachusetts Institute of Technology. The technology, Mr. Koh said, could "make supply chains more efficient and more secure." Wal-Mart and the Department of Defense have already mandated that their top 100 suppliers put the antennas on delivery pallets beginning in January. Radio tags on vehicles and passports could become a central tool in government efforts to create a database to track visitors to the United States. And companies are rushing to supply scanners, computer chips and other elements of the technology. The labels are called radio-frequency identification. As in automated highway toll collection systems, they consist of computer chips embedded into stickers that emit numbers when prompted by a nearby radio signal. In a supermarket, they might enable a scanner to read every item in a shopping cart at once and spit out a bill in seconds, though the technology to do that is still some distance off.
