if you need to use a card, you must first ask the cardholder to use the card for more than half a year and it has not expired. Some banks support card business, while others do not, depending on which bank you choose. For some banks, the previous credit card can only be a kind of financial proof, which can be used as an auxiliary certificate, but other credit cards cannot be handled directly by credit card. To handle the card business by card requires the applicant's ID card and previous credit card. If you can't handle the card by card, you need to handle the credit card by ordinary process, usually ID card, income certificate and financial proof. When you apply for a credit card, you can get all the information ready.
