it is illegal to lend a credit card to others. According to the regulations of the International Credit Card Organization and the People's Bank of China, credit cards and their accounts are only used by the cardholders approved by the issuing bank, and may not be provided, leased or lent to others. It is a crime of obstructing credit card management. Therefore, one's own credit card cannot be lent to others, and the credit card must be held by the handler himself and cannot be lent to others. Lending it to others is generally a violation of the use contract. It's not illegal, but it's against your contract with the bank. If you bear any responsibility for the third party because you borrow a card, the bank will not bear any responsibility, so don't lend others your own credit card.
