Once upon a time, we used to park at the roadside and someone that claimed to be a parking attendant will collect your money as the parking fees. But you will know that this person is an illegal parking attendant. But nowadays, there are official carparks which was originally an empty lot that have parking attendant at the entry entrance or exit. There is not even a “boom gate” but you know that you need to pay. This is what we called “Parking 1.0” – totally manual and you might be lucky of you also got a paper receipt from the parking attendant.
But when they introduced a “boom gate” which was electrically controlled, the parking system with a human parking attendant was upgraded into Parking 2.0. As we progressed, with the era of Internet and the application of eWallet, the parking system has now become very convenient to the drivers and the parking owner.
