Stop stores and airports from tracking your movements

Did you know that for several months Wal-Mart tested a facial recognition system that can pick an individual out of a crowd and track them automatically through a store? It’s true. Wal-Mart was mainly using the system to spot known shoplifters, but I’m sure you can think of more worrying purposes.

Facial recognition is one of many technologies that brick-and-mortar retailers are testing to get real-time data on their customers. Online stores can see exactly what products and ads a user looks at, but offline retailers traditionally know only what people buy. They want to change that so they can maximize their marketing and profits.

How retailers track you

While facial recognition is still in limited use, many retailers, and other locations with a lot of traffic like airports, are using Mobile Location Analytics to track your exact location. For example, an airport knows how much time you spent in a shop, moving through security or at the baggage claim. A store knows when you move from one department to another, or even linger in a certain aisle. How do they do this?
