Different credit cards have different installment time, different interest rates and no fixed interest. So, are the two credit lines of China Merchants Bank shared? Are the two credit lines of China Merchants Bank shared? According to the regulations of China Merchants Bank Credit Card Center, the credit card quota of China Merchants Bank is shared, and different credit cards share one account. All cards have bills, and cardholders can also use any credit card. In other words, two or more credit cards of China Merchants Bank and their accounts share a 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. Among them, credit card line sharing means that credit cards of the same bank and brand share the same line (generally the maximum line of one card). Although several cards have their own single card limit, the total overdraft in use cannot exceed the sharing limit of the brand credit card. The credit card sharing quota of China Merchants Bank is subject to the maximum credit card quota. If one of the credit cards has used the maximum amount, then the other two can't be swiped. Although the amount of credit cards held by cardholders is the same, the consumption amount and interest of these credit cards are calculated separately. In other words, the consumption amount and interest will be calculated separately and displayed separately on the bill. China Merchants Bank implements one-account repayment, and multiple credit cards consumed by cardholders can be repaid with one card instead of a single card.
