How to pay for Chongqing Rail Transit
The airport transport guide confirms that single-journey tickets are sold at CRT stations. Mobile payment is useful across Chongqing, but confirm the current rail-specific method at the station.
Simplest first ride
Buy a single-journey ticket at the CRT station and use the English station name or Chinese destination text if you need staff help.
Mobile payment setup
Chongqing's official guide explains how international visitors can link supported overseas cards to Alipay or WeChat Pay. Set this up before travel for shops and other supported payment points.
Keep a backup
Carry some RMB cash and do not assume every card or QR method works at every rail gate. Ask station staff for the current ticket option if needed.
