Here’s an eye-opening look at how closely (and eerily) Target tracks its customers’ purchases.
This isn’t the half of what stores can do, though. Before I got my current gig, I did a telephone interview with a company which made recognition software for in-store video systems. Supposedly this software could track customers as they made their way around the store, including how long a customer lingered on a particular aisle. It was Big Brother to the extreme and while I needed the work, I’m glad I didn’t have to get into that spooky stuff.
