I am a credit card clerk at a bank. The reason why I ask you to fill in your workplace when you first apply for a card is because the bank wants to confirm that you have financial resources and the ability to repay after using the card. Your previous workplace went bankrupt, but your credit card can still be used. It doesn't matter much. If your colleague uses his credit card without exchanging money, he will be blacklisted by the bank. If he is involved in loans at the bank in the future All types of businesses are affected. It has nothing to do with you whether he will pay back the money he has swiped on his credit card. It is definitely not the card he applied for using your ID card, so it has nothing to do with you. As for when he applied for the card, the emergency contact he filled in was you, and it has nothing to do with you. It doesn't matter. It has no effect on you.
