Your main job is to rent a car, and I also do it here. Give you some suggestions: First, for the safety of cars, don't be mortgaged or pawned by some people, which will be very troublesome, so every car should have GPRS positioning, and this positioning is credible. The function must have the basic function of cutting off oil and electricity, and ensure the quality. Don't use it when it's critical. Second, you can't trust anyone when you collect money. The deposit should be enough to take the car and renew the rent, and the character should be guaranteed. If necessary, you can find a reliable guarantor to minimize the risk, because if you like, if he drives a car, it is out of your control. Third, speeding and running a red light should be said in advance, and it will take ten days to pay you back. Tell him. As for the copy of the driver's license below, remember the date of car rental registration and the maintenance of the car, so I don't need to say more. The main ones are on it. I summed this up. I hope your business is prosperous!
