Layer 1: Two Mobile Wallets
Chengdu's payment landscape is dominated by Alipay and WeChat Pay, but they aren't interchangeable. Some small vendors only accept one. Install both on your phone before departure. Link each to a separate funding source—one to your home credit card, the other to a travel prepaid card. This way, if one app's connection times out (common in metro stations with weak signal), you can switch to the other. A traveler from Australia I assisted last month failed to scan at a Jinli street market stall; switching from WeChat to Alipay worked immediately because that vendor had a different QR provider.
Layer 2: Preloaded Cash as a Universal Fallback
Cash is still king in Chengdu's wet markets, some tea houses, and tiny souvenir shops. ATMs are plentiful near major tourist spots like Wuhou Shrine and People's Park, but they dispense only Chinese yuan (CNY) and sometimes charge high fees. Before you leave your hotel, withdraw 200–500 CNY in small bills (10 and 20 yuan notes). Large bills (100 yuan) are often rejected by street vendors who can't make change. This cash cushion saves you when both apps fail due to network issues or account freezes.
Layer 3: A Physical Card That Works in China
Your Visa or Mastercard from home may be accepted at chain hotels and upscale restaurants, but not at metro counters, convenience stores, or most taxis. Apply for a UnionPay card before your trip—many foreign banks issue them. If your bank doesn't, consider a travel card that can be loaded with CNY and used at ATMs with UnionPay acceptance. In Chengdu, the metro ticket machines accept only cash or UnionPay cards, not foreign cards. Without one, you're stuck in line at the customer service window.
