快速结论
Alipay worked until a Suzhou noodle shop showed a green WeChat-only QR—had to ask my hotel to order for me. Now I run both.
详细回答
Detailed Answer
What happened: Day 3 in Suzhou, a small noodle shop had only a WeChat Pay sticker—no blue Alipay logo. My Alipay scan returned an error. I had WeChat for chat but had never opened Wallet. The owner could not take my foreign card. I walked back to the hotel and ate there.
What fixed it: That evening I opened Me → Pay and Services → Wallet, bound the same Mastercard, and tested ¥8 at a FamilyMart. Same card worked in both apps.
Official answer: Merchants pick one rail. See WeChat Pay question and payment stack. Do both wallets in one sitting: payment checklist.
下一步
Enable WeChat Wallet tonight → bind card → do not assume Alipay scan works on green QR stickers.
怎么做
Finish Alipay bind first if you prefer that order.
Open WeChat Wallet (chat alone is not Pay).
At next stall, check sticker color/logo before you queue.
常见坑
Installing WeChat for chat but skipping Wallet until a shop refuses you.
Scanning a green WeChat QR with Alipay and blaming "China is broken."
Thinking one successful Alipay payment means 100% coverage.
可能变化的部分
Policies and app flows change—verify on official sources before you travel.
常见问题
Can I use only Alipay?
I tried—one WeChat-only shop was enough to change my mind.
Where is the neutral comparison?
