The Credit Card Center of Shanghai Pudong Development Bank grants you the maximum consumption quota and cash withdrawal quota according to the information provided when you apply. You can check the initial credit limit on the delivery cover of this card and the first month statement. Within this limit, you can freely use this card to sign accounts or withdraw cash. This credit line is shared by RMB and USD, and the main card and the auxiliary card are shared.

The so-called "shared line" means that all credit cards held by the same cardholder use a common line. For example, if you hold five credit cards from a bank with a credit line of 10000 yuan, then these five credit cards share the credit line of 10000 yuan. When you overdraw 2000 yuan with one card, you can also overdraw 8000 yuan with the other four cards.

Extended explanation: Credit line sharing means that credit cards of the same bank and brand share the same credit line (generally the highest credit line for one card). Although several cards have their own single credit limit, the total overdraft in use cannot exceed the shared credit limit of the brand credit card.
