PROBLEM TO BE SOLVED: To install the attribute information on a paying person in the communication terminal device of the paying person side in a high security state. SOLUTION: This system has a cryptographic key for setup generating part 13 for generating a cryptographic key for setup on the basis of an on-vehicle machine manufacturing ID, a cryptographic key for setup storing part 12 for storing the cryptographic key for setup, a cryptographic key for setup issuing part 14 for issuing the cryptographic key for setup to a manufacturer 4 while related to the manufacturing ID in order to install the cryptographic key for setup in an on-vehicle machine, an individual vehicle information receiving part 15 for receiving individual vehicle information together with the manufacturing ID from a setting up person 5 who performs setup, and a vehicle type code issuing part 21 for fetching the cryptographic key for setup on the basis of the manufacturing ID received by the part 15 and issuing the cryptographic key for set up together with a vehicle type code discriminated on the basis of the individual vehicle information to the person 5 in order to set up the vehicle type code in an on-vehicle machine 3. |
