Large-amount credit card payments are made through the online banking of the credit card issuing bank (the seller needs to open a credit card payment gateway and jump directly to the online banking page when paying). This is opposite to credit card fast payment. Credit card Quick payment is paid through a third-party payment platform (such as Alipay), so single, single-day, and single-month payments are subject to the limits of the third-party payment platform (although some third-party platforms no longer set quick payment limits for all users) , such as Alipay), while large-value credit card payments (online banking payments) are only subject to the online payment limits stipulated by the card-issuing bank, and the online payment function must be activated in the card-issuing bank's online banking before it can be used.
