The function of credit card secondary card

Many banks supported applicants to open secondary cards. Generally, parents applied for primary cards to open secondary cards for their children. The advantages of applying for a supplementary card for children are:

First, you can know the consumption of children in time. For example, the bank can provide three ways to remind consumers of supplementary cards by SMS, namely, to remind only the main cardholder, to remind only the supplementary cardholder and to remind both the main cardholder and the supplementary cardholder. Our suggestion is that parents can choose the third way, which not only ensures the safety of supplementary cardholders, but also facilitates the timely understanding of their children's consumption.

Secondly, parents can restrict their children's consumption by setting the amount of supplementary cards and the flow limit of funds. For the supplementary card, the amount is subordinate to the total amount of the main card. The initial setting of the bank is that the amount of the two cards is the same, and the amount is used.

However, it is best for parents to reset the amount of supplementary cards according to their family situation, so as to avoid excessive consumption of supplementary cards. The concepts of usage flow and quota are different, which refer to the total amount generated by the use of funds in credit card accounts.

In addition, parents can learn about the use of supplementary cards through online banking and credit card bills. The repayment of the supplementary card can also be made by the parents who hold the main card, which saves the expenses generated by the transfer of funds in different places.
