1. If you don’t sign the credit card application form, the bank will probably not approve your credit card. If it is approved, you should ask the bank’s customer service for an explanation.

2. If you usually use a credit card and it is convenient for repayment and other services, you can apply for one. I don’t know if you didn’t sign at the end of the contract when the bank required you to leave a reserved signature area. If so, carefully check whether it is marked on the periphery: This signature should be consistent with the signature on the card. If so, the credit card card should be signed. The handwriting must be consistent with this handwriting to avoid being disadvantageous to you in the event of a dispute. Also, read the terms of the contract carefully. If you don’t frequently use this kind of loan for consumption, there is no need to apply for it. After all, credit cards (debit cards) are always risky. You can go to a bank branch and ask the counter to destroy the application form in person (because the bank will not return the application form).

3. There should be no problem with the extra slip. If you have time, you can double check what kind of business it is (it must be no problem if it is related to the social security card. Follow the one about the credit card and ask if the card is not there. Will it have any impact on future business if approved?)
