RFIDs to Keep Tabs on U.S. Drugs

The New York Times > Health > 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.

Experts do not expect the technology to stop there. The adoption by the drug industry, they said in interviews, could be the leading edge of a change that will rid grocery stores of checkout lines, find lost luggage in airports, streamline warehousing and add a weapon in the battle against cargo theft.

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.

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.
