Do I need to go in person to apply for a bank card?

Whether I need to be present when handling bank cards generally depends on the type of bank cards I handle.

To apply for a savings card, you don't have to be present in person, you can entrust someone else to handle it. When handling a savings card, customers can bring their ID cards and ID cards of managers to the outlets of the bank business hall to apply for a card. Upon examination, the savings card can be processed.

If the application is for a credit card, the applicant must do it in person, and can't find someone else to do it. Because the application documents for credit card processing must be signed by the applicant himself, the bank will also review the application materials submitted by the applicant, and the credit card can be successfully processed only after the approval.
