If you’ve ever shopped online, you probably know that a lot of your data is being tracked by other companies. Like if you buy shoes from Amazon, you might start noticing shoe ads popping up on other websites you visit. Stuff like that. It’s a bit on the creepy side, but it’s sort of become the norm.

But did you know that your “data” can be tracked just by walking into a store? If you think that is even creepier – blame Wisconsin. Scanalytics, a startup based in Milwaukee, has begun selling businesses floor sensors that can track where you walk throughout a store. These sensors can detect a person’s footsteps towards a digital display, while tracking how long they stand in front of it before walking away. That would give the business more information on the best times to have displays out or when to hand out coupons.

I can definitely see why businesses would be interested in this technology, but as a consumer, it’s still pretty creepy to me. Not to sound like a guy who wears a tinfoil hat, but it's a bit unnerving to buy groceries knowing that my every step is being tracked. Does this cross a line? I'm not quite sure.

What do you think? Good idea or a step in the wrong direction?
