Taking China Merchants Bank's credit card as an example, the "fast credit card payment" business provided by our bank can be divided into two modes: large-amount fast payment and small-amount fast payment. The single transaction amount of small quick payment must be less than or equal to 500 yuan, and the single transaction amount of large quick payment can be greater than 500 yuan (the upper limit of single transaction depends on the partner). Alipay and Tenpay will prompt the limit when the cardholder pays quickly.
