The figures below come from WeChat official help and Tenpay. The in-app screen that day is the final call — that is where you see whether your home-country issuer will pass.
Visa / MastercardOfficially describedMeant for everyday shop payments. Official FAQ says red packets, person-to-person transfers, and wallet top-ups do not work on a foreign card.
JCBCandidateAlso appears on some municipal notices as an international brand. Issuers still refuse some cards.
Amex / Discover / DinersCandidateNames appear in official or city notices. That is not a promise they will bind. Keep a second card.
FeeOfficialTenpay: one payment of 200 yuan or less waives the international-card fee. Above 200 yuan the fee is 3% of the amount. Refunds use the same ratio.
LimitsAs of the help pageWeixin Pay help: 6,500 yuan per payment, 50,000 yuan per month, 65,000 yuan per year. FX follows the card network and issuing bank.
