The primary card and the secondary card belong to the same account and share the credit line. Most of the cardholders of the main card and the deputy card have a common property relationship, or know and trust each other, and there are agreements such as gift, entrustment and paid commitment between them. When the secondary card swipes the card, the primary card can see that all the debts incurred by the secondary card holder when using the credit card are borne by the primary card holder, and the primary card holder directly performs the debts to the card issuer or special unit. In the relationship between the main cardholder and the supplementary cardholder, the main cardholder is in a dominant position and has the right to decide to add or cancel supplementary cards, while the supplementary cardholder is in a subordinate position.
Supplementary cards can bring a lot of convenience to daily card swiping applications. When opening the main card, you need to open the secondary card at the same time, which not only facilitates the users of the secondary card to use the card, but also allows the main card to control the amount. It is a good choice for family financial products.
The main card and the auxiliary card of a bank card are both a kind of bank card, but the authority and usage limit of the auxiliary card are limited by the main card. Their differences are as follows:
1, card cancellation. The main cardholder has the right to request cancellation of his supplementary card; The holder of the secondary card cannot independently cancel or cancel the primary card.
2. Credit line. The credit limit of the main card is only subject to the requirements of the bank; The credit limit of the secondary card is specified by the cardholder of the primary card on the premise that it does not exceed the credit limit of the corresponding primary card. If the cardholder of the main card is not specified, the credit limit of the auxiliary card is the same as that of the main card.
