Merchants don't support credit card payment for the time being, which means that merchants can't use credit card payment when shopping or trading. This may be because the merchant's payment system is temporarily unable to handle credit card payment, or the merchant chooses not to accept credit card payment. Possible reasons include the cooperation between merchants and credit card payment institutions, technical failures, merchant policies, etc. If you want to pay by credit card, you can ask the merchant if there are other acceptable payment methods, such as debit card, Alipay and WeChat payment.
