Sen. Charles Schumer says federal authorities should regulate the practice of retailers using shoppers� smartphones to track their movement through a store.

Schumer, D-N.Y., said Sunday that the Federal Trade Commission should require that stores let shoppers opt out of being tracked.

Several major retailers use technology that allows them to track customers� movements through their stores by following Wi-Fi signals from smartphones.

Schumer said that shoppers who don�t want to be tracked must turn of their phones� Wi-Fi or leave the devices at home.
He called cellphone tracking �intrusive and unsettling.�

Schumer said at a Manhattan news conference that the FTC should step in and require an �opt-out� provision.

He said the tracking program is a deceptive trade practice because shoppers don�t know they are being tracked.
