In Time Magazine’s March issue, a Tech Briefing explained how retailers, such as supermarkets, can tempt shoppers with digital coupons based on each shopper’s location within a store.
The article explains that the technology is already built-in to certain smart phones in the form of a small transmitter called a “beacon.”
By using Bluetooth technology, “handsets can pinpoint their [shopper’s] position to within as little as 2 cm by receiving signals from the beacons. ”
Then the retailer can send special offers to the customer’s cell phone or simply monitor a shopper’s movements. Of course “they” won’t be able to see you unless you’ve installed their apps and granted them access… but for many, Big Brother is another step closer!
