How Retail Stores Track You Using Your Smartphone (and How to Stop It)
When you walk into a brick and mortar retail store like a Nordstrom, Cabela, or even Family Dollar, you're being tracked around the store. Not by an over-suspicious security guard, but by the store's wireless network, using your phone's Wi-Fi. The store then uses your phone to track you around the store, determine if you're a repeat visitor, see what departments you visit, and more. Here's how they do it, and how to stop them.
The New York Times broke the story earlier this week that a number of retail stores are either experimenting with or actively using technology that uses your phone's Wi-Fi to track your movements around the store. We're not talking about location within a few meters either—we're talking about exact location.
Nordstrom, the store that the New York Times focuses on in its piece (although it's not the only one doing this) installed sensors around some of its stores that would scan for smartphones with Wi-Fi turned on and scanning for networks. The sensors would then make note of the device's MAC address (an address that's unique to your phone) and use it to identify and follow the device as it moves about the store. Information about how frequently that MAC address visits the store, which departments it visits when it's in the store, how long it stays in each department, and how long it stays in the store. Granted, you are not your phone's MAC address, but if you carry your phone with you all the time, you may as well be. ................

.....So there are benefits and drawbacks. As with any technology, it could be used to help you score a bargain or get the best price on something, or to reward your loyalty for shopping at your favorite stores. ..............

They should be able to use Bluetooth as well as Wi-Fi to track.
