Every marketer knows that understanding your customers' habits and patterns is a key to success. That's why online tracking has been used extensively to build robust customer profiles, proving astonishing efficiency for marketers.
With facial recognition technology accurate enough to identify a visitor from a camera's video stream and quickly search hundreds of faces per second in a dataset of millions (even billions) of faces, impressive customer analytics techniques can come to offline word.
Once you are able to identify and individually recognize your visitors, you can learn a lot about their patterns and habits, like frequency of visit and route they take through your store. You can even create individual profiles for every visitor, granting you the ability to offer super-personalized targeted ads.
