Introduction

1.1

Purpose

For drivers who need time to do other things in their life than waiting for ticket and going to pay fees for
their cars, the Smart License Plate is a smart device that is embedded into the plate of the cars. The plate
will store the exact position of the driver by GPS connection, it will be synchronized with its owner’s
banking accounts, that will help drivers pay their fees automatically and they do not need to go to the
centers to pay anymore. The device will save a huge time for drivers, and save 400$ each month for the
parking area thanks to removing the ticket and keeping staff. Time to handle traffic situations will be
reduced 50% because government can know exactly where the car is to go in time. Unlike the current
traditional license plate with no utilities, our product will synchronize with drivers’ banking accounts to help
them pay their fees automatically, keep their safety on the road by the GPS tracking system.
