Moreover, according to the rules and regulations of credit cards, credit cards can only be used by credit cards themselves. Even giving it to relatives is illegal.
First, the amount in the credit card is not your own property. The amount of each credit card is assessed by the bank according to your personal qualifications and credit status, but it does not mean that this amount is your personal property. There used to be an application confirmation letter for handling credit cards, which clearly stated that it was not allowed to lend to others. Once found, the bank has the right to seal up the card and stop using it, and recover all the arrears and other expenses.
Second, lending credit cards to others brings high risks. In the process of use, in most cases, the customer needs to sign for confirmation. Since it is lent to others, you will sign the signature. Moreover, all the information of your credit card is under the control of the other party. If one day you get your credit card back, it's not safe. Your password and transaction information have been leaked to others.
Third, after the credit card is overdue, it can only be borne by itself. You know, credit cards are handled with ID cards. If the credit card is overdue, it will be directly included in your personal credit report. You are responsible for all interest and liquidated damages.
