This paper presents a system that allows users to reserve a parking lot by using their smartphones. The aim of this project is to shorten the time required to look for an empty parking lot, and resolve the congestion issue in car park at mall. When the smartphone is connected to the internet, the user is only required to make a reservation by paying the first-hour rate through PayPal. A parking lot will be reserved for the user for an hour. At the same time, a QR-Code will then be generated, and user can enter the car park anytime within the hour by using the QR-Code. Before the user exits the car park, the user only required to pay the balance through PayPal. This reduces the hassle of queuing up for in front the payment machine. After the payment, a new QR-Code will then be generated, and the user will exit the car park by using this new QR-Code.
