Relationship between supplementary card and main card
All debts incurred by the supplementary cardholder when using the credit card shall be borne by the main cardholder, and the main cardholder shall directly pay the debts to the card issuer or special unit. Therefore, the main card and the supplementary card mostly share property, or know and trust each other, and there are agreements such as gift, entrustment and paid commitment between them, which also determines that the main card and the supplementary card belong to the same account and share the credit line.
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. If the primary card is cancelled, the secondary card should be returned to the card issuer voluntarily. When the main cardholder requests to stop using the supplementary card midway, he should also return the supplementary card to the card issuer, and the outstanding debt will still be borne by the main cardholder.
The main card and the supplementary card share the same amount. If the amount is 5,000 yuan, the total credit card amount of the main card and the auxiliary card shall not exceed 5,000 yuan.
