Have you shopped in the new TESCO in Cambridge lately? Did you happen to buy a pack of razors from Gillette? If yes, then you also bought a smart chip
attached to the pack that automatically activated a small camera located on the ceiling. This camera most probably took a digital picture of you in
the act of taking the razor pack, and since the smart chip is so smart it also activated another camera, a few minutes later at the cashier, putting a
second picture of you into the store's database. All that without your knowledge.
