The function of credit card supplementary card

Many banks currently support applicants to open supplementary cards. Parents usually apply for the main card. Your own children open supplementary cards. The advantages of applying for a supplementary card for your children are:

First, you can learn about your children's consumption situation in a timely manner. For example, for supplementary card consumption SMS notification reminders, banks can provide three reminder methods: only reminding cardholders of the main card, reminding only cardholders of supplementary cards, and reminding cardholders of both main and supplementary cards at the same time. Our suggestion is that parents can choose the third method, which not only ensures the safety of supplementary card holders, but also facilitates timely understanding of their children's consumption status.

Secondly, parents can restrict their children’s consumption by setting additional card limits and fund usage flow limits. For the limit of the supplementary card, which is subordinate to the total limit of the main card, the bank's initial setting is that the two limits are the same, and the limit is always used.

However, it is best for parents to reset the limit of the supplementary card according to the family situation to avoid excessive consumption of the supplementary card. The concepts of usage flow and limit are different, which refers to the total amount generated by the use of funds in the credit card account.

In addition, parents can also learn about the usage of supplementary cards through online banking and credit card statements. The repayment of the supplementary card can also be made by the parent holding the main card. This method saves the cost of transferring funds to other places.
