In addition, the difference between the main card and the auxiliary card lies in:
1. Both the primary card and the secondary card will generate annual fees, but the annual fees of the secondary card will be cheaper than the primary card, about half.
However, at present, many banks' credit cards can be spent by credit card, and the annual fee can be exempted if a certain number of requirements are met.
2. The main card and the auxiliary card share the credit line of the main card. For example, if the amount of the main card is 10000 yuan, then the consumption of the secondary card is also deducted from this 10000 yuan.
3. Generally, it is not allowed for the amount of the secondary card to exceed the amount of the primary card.
Ownership: the ownership of the secondary card belongs to the primary card, and the primary card can perform any operation on the secondary card, including freezing and account cancellation.
4. The loss of the primary card will not affect the use of the secondary card. In addition to sharing the quota, the main card and the auxiliary card can basically be regarded as two independent cards. After the loss of the primary card is reported, the use of the secondary card is not affected, and vice versa.
5. Many applicants for supplementary cards are immediate family members (parents, spouses or children). For example, college students can't apply for credit cards, but they can apply for supplementary cards with their parents. Supplementary cards have the same ability to spend first and then repay. Of course, since the primary card and the secondary card have the same amount, it must be the parents who repay.
