ALBANY, N.Y. (AP) _ U.S. Sen. Charles Schumer says eight companies have agreed to measures that will let shoppers nationwide know when retailers are using their smartphones to track their movements through a store.
The New York Democrat criticized the practice in July. He tells The Associated Press on Tuesday that eight of the 10 leading location analytics companies have agreed to a new code of conduct.
It includes signs posted in stores to alert shoppers that tracking is being done and instructions on how to opt out.
Several major retailers use technology that allows them to trace activity in their stores by following Wi-Fi signals from phones.
The technology companies are Euclid, iInside, Mexia Interactive, Nomi, SOLOMO, Radius Networks, Brickstream and Turnstyle Solutions.
Shoppers can also turn off their phones' wireless connections.
