The number plate may also be used to show the registration number of the vehicle. a number plate is not used only on vehicle but also used in identifying other things like as cabin number, room number etc. There are many types of number plates which differ from one another in colour, quality and also on the mode of use. Each country tends to have it’s own ideas about the colour, size and appearance of their vehicle number plates and pass laws to ensure that everyone adheres to the regulations governing them. It is important that standards are kept as the cameras we rely on need standard plates.
