PURPOSE:To miniaturize a device, to reduce a fault rate and to provide a high security function in an identification code collating system. CONSTITUTION:A portable telephone 28 having an identification code and transmitting the identification code by radio, a radio equipment 21 receiving the identification code, a storage device 23 storing registered data on the owner of the portable telephone, a retrieval device 22 retrieving registered data from the identification code and a controller 24 controlling the system from retrieved and registered data are provided. Thus, the system can be constituted by an electronic circuit without the need of a mechanical device since the identification code is given to a collation device by radio, the device can be miniaturized and the fault rate can be reduced. |
