The main card and supplementary card*** share the same limit. For example, the credit limit of the main card is 10,000 yuan, and the credit limit of the supplementary card is also 10,000 yuan. If the main cardholder has used 5,000 yuan of the credit limit, the supplementary card can only use the remaining 5,000 yuan limit. In addition, the principal cardholder can specify a credit limit for supplementary cardholders. For example, you can apply for an supplementary card for your child with a credit limit of 10% of your (primary cardholder) credit limit.
