In a word, you can apply for a new credit card with your credit card. In general, there are two kinds of cards. One is to apply for a bank's credit card, and then apply for other types of credit cards in the bank; The other is to apply for another bank's credit card with a bank's credit card.

At present, the banks that can handle cards with cards are Bank of Communications, China Guangfa Bank, China Bank, Ping An Bank, Shanghai Pudong Development Bank and China Everbright Bank. These banks are required to hold other banks' credit cards for more than 1 year, which are in good condition and can be processed without overdue.

It should be noted that although it is very convenient to apply for a card by card, it is recommended that you prepare your ID card, income certificate and other necessary related materials.

If you apply for a credit card from an existing bank, the credit limit will generally consider your previous credit limit. At this time, you have prepared more income certificates, and many of them may win more credits for you.

If you apply for a credit card from another bank, you should bring your ID card and apply for it with your existing credit card, which is very helpful for your new credit card limit.
