This is because your proof materials are not enough for credit card approval, and the bank doesn't want to give you up as a customer, so you can enjoy the functions of credit card (such as discount of goods and establishment of credit record), but the amount is very low, only 1 cent
You can save money for consumption first, and the bank will invite you to issue a formal credit card again according to your spending power and financial factors.
I have such a card, but it has been cancelled! It's no use. CITIC's credit card is not good and the cost is high.
