1. Check the security code directly by SMS. After the general card is approved successfully, the bank will send a short message to inform the virtual card that the approval is successful. The short message contains important information such as credit card number and security code, which are important vouchers for credit card transactions.
2. Call the customer service of the issuing bank. General customer service will require the user to provide the ID number reserved when handling the card, so as to verify the user's identity information and help the user to query the security code after confirmation.
