Paying for things in mainland China as a visitor

A mobile payment is not a card transaction. It requires the app to open, authenticate, generate or scan a code, and confirm with a server. Every one of those steps needs a live connection, which means that losing data does not merely inconvenience you — it removes your ability to pay at the counter you are standing at. This is the single most important thing to understand before arriving. Connectivity is not a separate item on the packing list from money; in practice they are the same item.

The registration and card-linking steps are considerably easier on a connection you trust, at a desk, with time.

Cash remains legal tender and is accepted, including by taxis and smaller businesses. Carrying some is not a fallback of last resort so much as ordinary prudence, particularly outside the largest cities. International cards are accepted at hotels, larger restaurants, and transport hubs, though less widely than a visitor might expect. Treating cards as a partial fallback rather than a complete one matches how they behave in practice.

Coverage in Chinese cities is generally strong. The places where a visitor most often loses data are underground stations, the interior of very large venues, and the long rural stretches between cities on rail routes. These are predictable, so the preparation is predictable too: settle payments and check directions before descending or departing, rather than while in motion. Arriving with data that already works, rather than data you plan to arrange after landing, removes the awkward first hours in which none of the above is possible.
