British Airways has signed up for ViewTags, reusable electronic baggage tags that flyers attach to their luggage before getting to the airport. Qatar Airways was the first to test the technology last year. ViewTag has been approved by the International Air Transport Association and features radio frequency identification (RFID) technology, Bluetooth LE, and a digital display to show the kind of flight information usually found on the paper tag attached to luggage by airport staff at check-in. Passengers transmit their flight information to the reusable luggage tag from a smartphone app, then simply drop their bags off at a designated place, without having to wait in a line. The company also says that the technology allows travelers to keep track of where the luggage throughout the baggage handling process.
