Credit card line sharing means that the same bank credit card held by the same cardholder uses a common line. The maximum amount that a cardholder can use is subject to the maximum amount of all credit cards under his name. In other words, the credit cards held by the same cardholder can use a common credit limit, and the credit limit is shared by higher credit cards. Although each credit card has its own single credit limit, the total overdraft in use cannot exceed the shared credit limit of the brand credit card.
