Solemn reminder: The credit card can only be used by yourself and cannot be lent to others. This is expressly stipulated in bank regulations. In this case, the bank will only contact the card holder to repay the money, and will not contact the colleague because the signature is signed by him.
If you must lend it to others, 1. Use password transactions, because most domestic credit cards use password transactions. The signature is only to check whether it is the name of the cardholder, and the handwriting is generally not taken seriously. 2. Be careful when lending to others, because if you fail to repay the loan overdue, you have to bear it yourself. Therefore, if friends, colleagues, etc. need to borrow money, they must write an IOU with it written in black and white, just in case. Warm reminder: If your family members need to borrow money, they can directly apply for an additional card. They will enjoy the same points accumulation and the repayment will also be made by the primary cardholder.
