To apply for a supplementary card of ABC's credit card, one of the most important prerequisites needs to be met: the applicant's immediate family members already hold the main card of the bank's credit card. The so-called immediate family members refer to the parents, children and spouses of the applicant, and the types of supplementary cards applied by the applicant should be exactly the same as the types of main cards held by their immediate family members.

In this technology, the supplementary card applicant must also meet an age condition-14 years old or above.

You can't apply online for ABC credit card. You can go to the nearest Agricultural Bank outlet to handle it. You need to prepare the ID card of the primary cardholder and the ID card of the secondary cardholder, and fill in a complete credit card application form (both parties must have autographs).
