Travelers can tag their bags before arriving at the airport.
Checking in your bags will soon be easier than ever. British Airways will be the next major airline to roll out RFID luggage tracking for its passengers. Travelers with a ViewTag can tag their bags before even arriving at the airport. After checking-in with BA’s mobile app, you’ll be able to sync your flight information to your bag with your smartphone.
British Airways passengers can pre-order their RFID luggage tags directly from the airline, which are available at the introductory price of £63 (roughly $80). The reusable bag tags are equipped with Bluetooth Low Energy and an E Ink display that shows your flight information. Each tag is rated for over 3,000 screen changes and doesn’t need to be recharged. At present, the tags can only be used on direct flights.
