Abstract: The present invention relates to a multifunctional identification and management device for vehicles that implants a chip in the automobile and the license plate for identification and comparison with comparison numbers or data provided. By comparing the comparison number built in the two chips, a specific detector sends out an error message if the numbers do not match. If the comparison numbers or data matches, the policemen, security guard or parking lot manager can examine the identity of the automobile, ban or fine for violating the law as well as emit unusual frequency or signal to notify the police station automatically, so as to enhance working performance and prevent automobiles and license plate from being stolen and being used in a crime.
