The advantage of the Bank of China Study Abroad Letter Card is that you can set up a main card and a supplementary card. That is, the main card will repay the expenses of the main card and the supplementary card. To put it simply, the child spends money. The parents are responsible for repaying the loan, and the main card is responsible for the repayment based on the consumption of the supplementary card.

The main card’s own consumption will also be repaid by the main card. That is, if two people consume, it is enough for one person to repay, and there is no need to assign two people to repay.

Repayment and credit investigation are the responsibility of the main cardholder, and the supplementary card has no responsibility at all, so this can bring some convenience to your children.

Furthermore, the cash in the credit card's supplementary card is interoperable and can be spent with each other. When applying for the supplementary card, the supplementary card and the main card need to be registered with different ID cards. , main card applicants need to apply for the main card first, and then apply for supplementary cards for their relatives and friends. So the above is one of the benefits of the Bank of China Overseas Student Card.
