Usually when you sign the IOU, you are asked to sign a credit card application form conveniently, and just sign it. Other information (proof of income, ID card, company name and home address, etc.). ) you submitted it when you applied for a loan.

Our bank will do the same for loans, but some banks have to explain to customers, and some don't.

No, just cancel the credit card. It's okay.
