1. The main card is the credit card I applied for;

2. The secondary card is a credit card hanging under the main card.

The cardholder is different from the main cardholder. These two Kakas are the same in nature, category and credit line. If you spend, the consumption limit is also reflected in the main card. A main card can only handle two sub-cards at most.

All debts incurred by the deputy cardholder when using the Peony Card shall be borne by the main cardholder, who shall directly perform the debts to the card issuer or special unit. Therefore, the relationship between the main cardholder and the deputy cardholder is mostly common property, or mutual understanding and trust, and there are agreements such as gift, entrustment and paid commitment between them, which also determines that the main cardholder and the deputy cardholder belong to the same account.

In the relationship between primary and secondary cardholders, the primary cardholder is in a dominant position and has the right to decide to add or cancel secondary cardholders, while the secondary cardholder is in a subordinate position. If the primary card is cancelled, the secondary card should be returned to the card issuer voluntarily. When the cardholder of the primary card requests to stop using the secondary card, he should also return the secondary card to the card issuer, and the cardholder of the primary card is still responsible for its outstanding debts.
