The registration number consisting of alphabets and numerals are placed on a plate called number plate. Later the simple number plate has been modified with security number plate with special features providing efficient monitoring and management.
[0005] Most systems used are manual clearance systems using one or more means of physical verification, physical pass verification, etc. but proving time and manpower consuming. Therefore, it is common to provide more efficient and accurate solution to the problem using technological means as alternative to existing manual methods.
