Chengdu's public transport payment is neatly unified by the Tianfutong system (天府通), which works on both the metro and city buses. For a short visitor the simplest choice is a phone QR code, while a longer stay may justify a plastic card. Once set up, you simply tap or scan at the gate or bus door and go, no fumbling with tickets or cash. This guide explains the options so you can pick the right one before your first metro ride.
The Phone QR Code, Best for Visitors
Open the Tianfutong app, or the Chengdu Metro or bus mini program inside WeChat or Alipay, and generate a ride QR code. For the metro, scan it on the way in and on the way out; the correct fare is calculated automatically. On buses, scan once when you board. The code works offline once generated, which is handy in the subway where mobile signal is weak. Link a Chinese payment method; a foreign card can be added in some apps but not all, so check before you travel and top up if needed.
The Plastic Tianfutong Card
A physical Tianfutong card is sold at metro station service desks and convenience stores, and you top it up with cash or Chinese payment. Tap it at the metro gate and on the bus. It is convenient if you do not want to manage apps, but you may be left with leftover value at the end of your trip, and refunds are cumbersome. For most short visitors, the phone QR code is simpler and cheaper, because you pay exactly what you ride.
Tips to Avoid Headaches
- Generate the metro QR code before you reach the gate, because signal underground can be patchy.
- On the bus, hold the phone steady against the reader until it beeps green.
- If a QR code fails, ask station staff; English is limited but they will usually help.
- Keep the same payment method ready across metro and bus so you do not juggle two apps.
- Check your balance or payment method before a long trip so you are not stuck at the gate.
Discounts and Use Beyond Chengdu
Repeated metro and bus trips do not carry a big discount, but the convenience of one QR code is the real saving. The same Tianfutong system also works on some shared bikes and small shops in town. If you travel to other cities, their local transit apps may differ, so download the regional app on arrival. Foreign cards still have limited support, so keep a backup method. Charge your phone before a long day of scanning.
Common Glitches and Fixes
If the QR code shows a red error at the gate, wait ten seconds and try again, or ask staff to open it. Make sure your phone has battery, since a dead phone means no ride. Update the app before your trip. On buses, hold the screen close to the reader, not at an angle. If you add a foreign card and it fails, keep a backup method. The same code works on the metro and most buses, so you do not need two apps. Keep a screenshot of your QR code for weak signal.
