ETCP can't enter two cars. Only one car can be bound to one card. If multiple vehicles need to be handled, they can be handled by the same person. To unbind a vehicle from ETCP, you need to click on the My Site column of Alipay ETCP service window, then click on my account, then click on vehicle management, and then click on the left to unbind the vehicle.

Etcp parking system principle

When the vehicle of the fixed card user enters the parking lot, the access controller actively detects the entry of the vehicle and whether the card is valid. If it is valid, the gate is opened and vehicles can enter the parking lot. The camera captures the photos of the vehicle and stores them in the management computer. When the vehicle leaves the parking lot, the exit controller automatically detects the arrival of the vehicle and judges the validity of the card. If it is effective, open the gate, trigger the exit camera to capture the vehicle, and the vehicle can leave the parking lot.
