Major retailers have reportedly taken serious steps to gather data on all of our behavior while we walk inside their stores.
Nordstrom is admitting that last fall it started testing technology that allows it to track the movements of customers.
By following Wi-Fi signals from their Smartphones.
A company spokeswoman says when Nordstrom posted a sign telling customers they complained in that it ended the experiment and today.
Morgan Wright is a cyber security analyst former advisor to the State Department and live with a -- Morgan thanks.
I show up this is kind of weird I mean -- Nordstrom is letting us know that Norstrom was testing it but what can make -- what can they know from this.
Won't show what they can get is actually information you would not otherwise voluntary disclosed to them about your shopping -- -- how long you've let's stay in a certain area what things you buy what's your preferences are your form of payment so.
Isn't as long as they -- -- you with a unique identifier which they can do for example through the phone.
They can learn so much about you about things you wouldn't otherwise volunteer to them if they try to do a survey at the front of the store with you.
And I guess the benefit for the story is they could -- -- specialized advertising or or one.
Yeah and actually if you actually if for example -- your mother stores have an application so if you have their happened here in store.
Because they know precisely where you're at -- -- can start serving you up advertising and an understanding hey.
Some of this technology show episode where it actually can determine it may be cured of that -- decide that you need beer or whiskey instead of you know -- magazine you're gonna by itself.
I mean they're really giving detail about this and that generates a lot of privacy concerns about how to white opt out how to I keep people from tracking me what -- still wanna shop at that store.
So what do I need to do do it turned it Bluetooth Wi-Fi all that if you still have your forged here -- -- can they do it that way are now.
Yeah it depends on some of the technology one of the waste Norstrom was tracking you a lot of the phones have the Wi-Fi signal and there and there's a setting that -- search for a Wi-Fi network.
So what's your kind of pinging it tracks it because -- you're trying to find an access point.
-- shut that off and only -- to -- networks there's probably less of a chance and so the cellphone signal will be less accurate so you know it's gonna be harder to do that.
But the point about it is your phone is unique they contract -- can see the number times you returned to the store.
Dates times locations frequency so there's many things are getting about two you may not want them to now.
All right Morgan thank you very much.
