The term wallet in the context of Chengdu typically refers to the city's widespread adoption of digital and mobile payment ecosystems, such as Alipay, WeChat Pay, and the local Tianfu Tong card. As a major Chinese megacity, Chengdu has transitioned into a nearly cashless society where mobile wallets are the primary method for everything from high-end shopping to buying street food. Furthermore, the city has recently upgraded its infrastructure to support "moving wallets" and contactless NFC payments, such as Apple Pay and foreign-issued bank cards, directly at metro and bus turnstiles. For international travelers, the "Chengdu Wallet" experience is facilitated by the Overseas Visitors Payment Service Center at Tianfu International Airport, which provides specialized RMB wallets and helps visitors link international credit cards to digital payment apps to ensure seamless navigation and transactions throughout the city.
