The two credit cards (master cards) of ICBC are the same account and a set of cards issued by ICBC. Two cards use the account and enjoy the credit line.

① The so-called "* * * credit line" means that all credit cards held by the same cardholder use the same credit line;

(2) For example, if you hold five credit cards from a bank with a credit line of 10000 yuan, then these five credit cards * * * use this credit line of 10000 yuan. When you overdraw 2000 yuan with one card, you can also overdraw 8000 yuan with the other four cards;

(3) Credit line * * * refers to the credit card of the same bank and the same brand * * * enjoying the same credit line (generally, the maximum credit line for one card). Although several cards have their own single card limit, the total overdraft in use cannot exceed the * * * enjoyment limit of the brand credit card.
