The "credit card quick payment" business provided by our bank is divided into two modes: "large amount quick payment" and "small amount quick payment". The single transaction amount of small amount quick payment must be less than or equal to RMB 500. , the single transaction amount of large-amount quick payment can be greater than RMB 500 (the upper limit of a single transaction depends on the partner). The third-party payment platform and its cooperating merchants agree on which fast payment mode to use, and cardholders cannot choose on their own. Alipay will remind the cardholder of the limit when making a quick payment.
