When CITIC cardholders engage in car rental transactions abroad, merchants swipe their cards for pre-authorization, and at the same time, they need to sign a car rental service agreement, which the cardholders should perform according to the relevant contents of the agreement. If they violate the agreement, some expenses may be incurred, including the expenses will be deducted if they violate the agreement during the exercise. So when you choose to rent a car, you should pay attention to the contents of the agreement, including: the place to pick up the car, the time to pick up the car, and the time to return the car.
