I have read on the German Frequent Traveller Forum that if as a foreigner you reserve the train ticket via the 12306 App or website, you do not need to queue with your passport at the platform entry/exit, but you can use your Smartphone QR-code instead. On the other hand side using Trip.com to book the train ticket (+fee per booking) and use the passport one can skip the sometimes endless queues.
