Big retailers are tracking your phone's Wi-Fi signal
They're using a service that follows shoppers to figure out their buying patterns.
Just a suggestion.
Without their knowledge, the 40% to 70% of all shoppers who have stepped into Nordstrom (JWN) and other outlets with their smartphones on have been tracked by a company called Euclid Analytics through their phones' Wi-Fi requests. Euclid then uses that data to determine specific departments a shopper visits and how long a shopper spends in each department.
Nordstrom told a CBS (CBS) affiliate in Dallas that such information gives it "a better sense of customer foot traffic," but it has since announced it is ceasing its use of Euclid's tracking system. The New York Times speculates that retailers could use that data to shift high-end and downmarket items around their stores based on who walks by them. A Home Depot (HD) spokesman said that while that retailer once tested Euclid's tracking product a handful of its stores, it no longer uses it.
Shoppers looking to go untracked have to turn off their Wi-Fi or turn off their phones completely. If those consumers want to opt out, they have to go to a Euclid site -- whose existence they may not be aware of -- and tell Euclid they want out of the service they weren't asked to participate in.
The good news is that, once users opt out, their information is wiped from Euclid's database along with all of their phones' records. The bad news is users not only have to dig around for their phone's "MAC address," the code that identifies their device to a network, but they have to provide that code to Euclid to get scrubbed from its files.
Although Euclid is tracking 50 million devices in 4,000 locations, it assures shoppers that it doesn't cull data about "who you are, whom you call or the websites you visit." Shoppers' anonymous data is bundled with data from other individuals, resulting in an aggregate report of anonymous information.
Still, if customers want to be tracked and have their spending habits used for marketing purposes, they can just shop online.

There is an app which turns your wi fi off when you move away from your wi fi hot spot then back on when you return. This saves your battery and ensures no one is tracking you.
This article is misleading;
Every WiFi device emits an identifier called a MAC address. This address is part of the protocol by which a device discovers and connects to a WiFi access point.
Your MAC address can be "seen" by any Wireless access point in any office, store or public location anywhere you go - its just how it works. Its also not limited just to your phone. Your Kindle, Tablet, Laptop and any other wireless enabled device works exactly the same way.
However, there is ABSOLUTELY NO personally identifiable information in a MAC address and NO correlation between your MAC address and your identity. This technique is used by retailers to better lay out their stores in the hope of providing better customer experiences for the consumer - that's what retailing is all about!!
There are hi-tech ways to link a MAC address to a phone number using illegal methods, however no major retailer in the US would stoop to such measures and if they did. they would face unbelievable consequences from the FCC.
