Hello, generally speaking, the national law does not allow stealing other people's credit cards. If the credit in your hand is approved by your family, then it is not a crime for you to use it, but it is allowed. Furthermore, you are not allowed to use someone else's credit card in the bank, because if the cardholder goes to the bank for reconciliation and finds that the signature on the consumption receipt is not the cardholder's, then the cardholder can claim compensation from the bank for this transaction. Of course, banks will also call the police to find people who steal credit cards. In fact, people always do this in real life. I can only advise you not to do this. If you are a family member, you can apply for a supplementary card. If you have to use someone else's credit card, please write your signature in the cardholder's name. If there is any risk, please bear it yourself. I hope I can help you.
