How Do I Verify a Credit Card to Be Added?

When you add a credit card, the corresponding bank page will be displayed for authentication. The following uses a MasterCard credit card as an example to describe the authentication steps:

1. Confirm the credit card information and enter the security code and password.

   The security code is a three-digit number on the back of the card.

2. The bank system sends a verification code to your mobile phone.
3. After you enter the verification code, a result is returned. If the authentication fails, contact the issuing bank to learn about information of the error.
