At first, it sounded great. You walk around a city and cunningly hidden Bluetooth beacons sense your phone and use trigonometry to calculate your exact position at all times. They bring indoor mapping and navigation to malls, airports and even to specific shops and stores. They allow blind people to navigate. You can use them with your phone to unlock doors, be guided to a specific library book, be micro-billed according to how long you spend in a cinema or on a train, or be messaged about a museum exhibit/zoo animal/historic building you're standing in front of.
