My mother applied for a credit card with her ID card. Now I'm using it. Can I sign my name on the back of the credit card instead of my mother's name?
It's best to sign your mother's name, because the owner of this credit card is your mother. In some places, you don't need to show the cardholder's ID card to withdraw money or spend a lot of money with a credit card. I suggest you apply for a supplementary card so that you can sign your name and spend it aboveboard.
