Thanks to GPS, the apps on your phone have long been able to determine your general location. But what if they could do so with enough precision that a supermarket, say, could tempt you with digital coupons depending on whether you were hovering near the white bread or the bagels?
It may sound far-fetched, but there’s a good chance the technology is already built into your iPhone or Android device. All it takes for retailers to tap into it are small, inexpensive transmitters called beacons. Here’s how it works: using Bluetooth technology, handsets can pinpoint their position to within as little as 2 cm by receiving signals from the beacons stores install.
