Shared credit line

Shared credit line means that two or more credit cards and their accounts share the same credit line. When the consumption of any card and account reaches a certain amount, the available credit limit of these cards and accounts will be reduced accordingly.

Let's give an example. Suppose a cardholder holds two different types of credit cards A and B from the same issuing bank. A credit card received a credit line of 10000 yuan when applying, and the credit line was less than or equal to A card when applying for B credit card. After spending 4000 yuan with card A, if you use card B again, you can only use the limit of 10000-4000.

If the B card only gets a quota of 5,000 yuan at the time of approval, then no matter how high the quota of the A card is, you can only spend 5,000 yuan at most when using the B card.
