The online banking of China Construction Bank has added a "virtual card" project (my account-virtual card). But the website does not describe its related information. Specially consulted the customer service of CCB, and learned that the virtual card is a new non-physical card of CCB, which can set a fixed amount, validity period, CVV code, password and so on. , and can be used for overseas payment (for example, RMB payment will automatically purchase foreign exchange). In this way, friends who don't have dual-currency credit cards can pay overseas in the future. "Dragon Card Virtual Card" is a debit card product specially used for online payment and domestic and overseas payment by our individual customers with the current account (except credit card) signed by our online banking as the card opening source account in accordance with the registration requirements of real-name registration system. This product has no physical card, only account and no interest. Overseas shopping websites use CVV code. You don't need to enter a password for online shopping abroad. Just enter the CVV code.
