Hello, the due date of a credit card has nothing to do with when the card was opened. After opening the card, you can log in to the credit card website/, click "Online Banking Login" on the right, enter the ID number (or card number), query password and additional code. After logging in to online banking, check the credit card information in "Account Management" - "Account Inquiry" Information such as the payment due date of the current period, monthly bill date, credit limit, available limit, etc.

If you have any other questions, you can also log in to the online customer service: /cmu/icslogin.aspx?from=B&logincmu=0. Thank you very much for your attention and support to our bank!
