A staffer scans a battery-less electronic luggage tag in Shanghai Hongqiao International Airport yesterday. China Eastern Airlines yesterday launched the world’s first battery-less electronic luggage tags, which allow passengers to complete the baggage check-in process at home or on their way to the airport through an application on their mobile phones. The built-in RFID (radio frequency identification) chip in the tag can also help passengers determine the exact location of their baggage. The Shanghai-based carrier will release 4,000 luggage tags for free. Passengers are welcome to register their interest in using the product through the China Eastern app. Registrations will begin in August. The special tags are currently only available on direct flights between the Hongqiao airport and Beijing Capital International Airport.China News Service
