Starting from tomorrow, Chongqing Rail Transit and Tianjin Rail Transit will realize the interconnection of QR codes.

Thanks to CTOnews.com netizen JackZYH for the clue delivery! CTOnews.com, Sept. 8, according to the official Wechat account of "Chongqing Rail Transit", passengers can use the QR code of "Yu Changxing" App or "Tianjin Metro" App in Chongqing or Tianjin from tomorrow (September 9).

At present, Chongqing rail transit has achieved interconnection with Beijing, Shanghai, Guangzhou, Chengdu and other cities. After the interconnection of Chongqing and Tianjin rail transit QR codes, citizens commuting between the two cities no longer need to download additional App.

The rail transit QR codes between Chongqing and Tianjin are interconnected, covering all stations operated by Chongqing and Tianjin rail transit, and follow the principle of preferential localization when in use, that is, passengers do not enjoy local concessions when using "Yu Changxing" App to ride Tianjin urban rail transit.

CTOnews.com learned that passengers using the "Yuchangxing" App or the "Tianjin Metro" App need to upgrade to the latest version and switch to the Tianjin Metro or Chongqing Rail Transit ride page to activate the Transit QR Code function according to the guidelines.
