If the credit card is required by the bank without a password, then it should be a signature card when applying. It requires you to sign on the back of the card. If there is a signature on the back of the card, you can report the loss first and verify it after applying. For handwriting, please ask an authoritative organization to verify that it is not your signature when making a purchase. Generally, banks and merchants will resolve the matter satisfactorily; if that fails, you can take legal action.
In foreign countries, signature cards are considered more secure than password cards. , it just requires merchants to strictly check signatures, and merchants must be held responsible for their negligence; it’s just that many merchants have ignored it.
I wish you a speedy resolution!
