A radio communication module to be installed on a license plate of a
vehicle has a module body and a removal protector. The module body is
provided with a memory device, which stores a vehicle information, and a
radio communication portion, which transmits and receives an
electromagnetic wave to exchange the vehicle information with an outer
apparatus. The removal protector is for protecting the module body from a
detachment from the license plate to prevent the vehicle information from
being used by a third person.
