If CCB E pays for credit card online transactions, it generally uses the account payment function (you will need to enter credit card information to open it when paying online for the first time, and then you only need to directly complete it by means of "card number+mobile phone dynamic verification code", which is very safe and simple to operate. ) There is a certain limit. The daily limit is 5, yuan per card, so online shopping should be enough at ordinary times ~ And some e-ticket merchants, such as travel and air tickets, have a higher limit, which depends on the actual payment website ~

Of course, an important function of e-payment card is to switch transactions and set the limit of a single transaction (within the limit of the merchant website).
