Researcher: RFID Tags Can Spy on Consumers
RFID—U.S.August 17, 2010
The electronic tracking tags some retailers are putting in their products could threaten consumers' privacy, says a researcher from Purdue University. One major retailer is planning on attaching the tags to some of its products starting this month, The Chicago Tribune reports, raising concerns among some privacy advocates that the discarded RFID tags could be tracked and even reveal what products are in a consumer's home. Information security expert Eugene Spafford says companies can use the tags to track what consumers have purchased without alerting them that they're being spied on, and relatively inexpensive devices can read tags from hundreds of feet away.
