First of all, call to control your card and explain the situation, so that even after repayment, the card will not be used in networked credit card readers and ATM machines. If you are insured, please ask the bank to temporarily reduce your credit limit to 0 (usually up to 3 months), and you can resume it when things are solved (note that it is a temporary adjustment, and if it is changed to permanent, it will be re-examined later).

Or you can report the loss directly, then the card that reported the loss will be invalidated directly. But don't lie to the bank if any cards are lost or stolen. Because to withdraw cash, you must have a password. You even told your friend the password! The bank will not believe it. Moreover, the bank can access the purchase order and cash withdrawal video, and you will know the truth as soon as you check it.

When you apply for a card, all bank application forms will have an agreement. One of them is that the credit card you apply for can only be used by yourself (including your family). If you lend it to others, all risks and losses will be borne by the cardholder.

According to the above article, if you can't find your friends and can't repay them, you can only repay the consumer money yourself first, and the bank will not care if you lend it to others.

Finally, solve economic disputes with friends. Try to communicate with friends and explain the situation. If a friend really has practical difficulties, then help him if he has the ability. If you are not careful, please don't hesitate to call the police directly. You can ask the police to contact the bank for help.
