Swipe someone else’s business card to sign the name of the credit card holder. Use someone else's credit card and swipe the card signature to sign the name of the credit card holder. After the cardholder gets the Dragon Card credit card, the cardholder should immediately sign in the signature column (the signature cannot be altered, use a ballpoint pen). This signature uses the cardholder's "signature" in the application form, and this signature must also be used for offline card transactions for verification.
