Hainan has started piloting E-ticket in its island-looping high-speed line, reports the China News Service.
The latest trial allows people to check in without producing a paper ticket, which was previously necessary even for passengers who have bought tickets online.
Starting November 22, Hainan locals who succeed in purchasing an island-looping high-speed ticket will have access to an information sheet, which includes a QR code.
They can then check in by swiping the QR code, whether via an electronic or printed version.
Swiping ID cards, or a QR code generated by an official app on mobile phones, are also available for station check-in.
This is reportedly part of China's move towards "paperless tickets" and is expected to see a nationwide promotion according to Chinese railway authorities.
