Yes Wechat can return the credit card to others, receive the repayment invitation letter sent by friends, enter the credit card repayment page through the repayment invitation letter, confirm that the other party is the object to help repay, and confirm the repayment amount, thus helping the other party to repay. Users can't directly bind other people's credit cards, because users' micro-signals can only bind their own bank cards after completing real-name authentication.
