According to Article 9 of the Pacific Credit Card Charter of Bank of Communications:
The credit line of personal card master card and its subsidiary cards, multiple personal card master cards under the same cardholder's name, multiple unit cards of the same applicant and multiple currency accounts of multi-currency cards are all managed in a consolidated manner and shared in line.
Unless otherwise stipulated by the card issuer, the total credit line actually used by each card (account) shall not exceed the maximum credit line in each card (account) under the premise of being limited by the credit line of each card (account) respectively.
For example, the credit limit of the main card is 10000 yuan, which is the common credit limit of the main card and the auxiliary card. In other words, the main card only costs 5000 yuan, and the auxiliary card can cost another 5000 yuan. If the secondary card is also swiped with 5000 yuan, then the credit lines of both cards are gone.
Extended data:
All receipts, payments and expenses arising from the cardholder's use of the personal card main card and its supplementary cards are credited to the main card account. The cardholder of the main card shall be responsible for all repayments of the main card and its supplementary cards;
Supplementary card holders shall be jointly and severally liable for repayment of the arrears of their supplementary cards. All income and expenses incurred by each designated claimant who uses the company card are recorded in the company card account. The applicant shall be responsible for repaying all the payables of the company card.
The credit card belongs to the card issuer and is only for the cardholder's own use, and may not be rented, lent or given to others for use. Credit cards are only used in the field of personal consumption, and may not be used for non-purposes such as production, operation and investment.
In the field of consumption, business cards can also be used for daily business expenses and financial reimbursement such as travel and office procurement of budget units. Foreign currency cards and multi-currency cards are only used for consumption payment under the current account stipulated by the State Administration of Foreign Exchange abroad, and may not be used for payment of other transactions.
