Two airlines to use e-tags at Daxing Intl Airport

China Eastern Airlines and China Southern Airlines are planning to introduce battery-free electronic baggage-checking tags, that allow passengers to track the luggage status on their mobile phones, at the Beijing Daxing International Airport from next month.

Passengers can apply for e-tags on their cellphone apps. The e-tag is similar in size to an iPhone 8, and is like an ID card for the suitcase. When passengers arrive at the airport, they can self-check-in the luggage with the e-tag and self-service machines, and check luggage status by scanning the bar code, the two State-owned carriers said.

Through the apps, the systems will generate bag tag numbers and transmit the data to the e-tag through Bluetooth. After a few seconds, the electronic ink screen of the bag tag will display information such as the bar code and flight numbers.
