Train tickets sure, for the high speed rail, but metro? Not in Shanghai at least

Metro ticket machines in Beijing won't sell a ticket until you've scanned an identity card.

Tourists must wait at the ticket window. Foreigners aren't usually asked to show the passport unless they look Chinese.

No need to wait at no window. After you activate Alipay, just click on "Transport" and create a metro card for Beijing. Scan code on enter, scan on exit, pay the sweet low fare automatically. One app, 30+ cities.

"Activating Alipay" requires using an identity card or passport.

You don't have to wait at the ticket window though. Privacy? Maybe not. But convenience? At every corner.
