Abstract:
1. An electronic device control system, comprising: data preparation means for preparing and outputting operation data, each said operation data being prepared in association with, and being outputted from said data preparation means together with a first identification data that uniquely identifies said each operation data and is different in each instance of outputting; an electronic device for receiving from said data preparation means said operation data and said first identification data associated with said operation data, and for carrying out processing based on said operation data in response to an input of a second identification data, said second identification data corresponding to said first identification data prepared in association with said operation data; and a portable data storage means for receiving from said data preparation means and storing said first identification data as said second identification data for identifying said portable data storage means, said first identification data prepared in association with said operation data and output to said electronic device therewith by said data preparation means, wherein said portable data storage means automatically transmits said second identification data stored on said portable data storage means to said electronic device when said portable data storage means is brought within a preselected distance of said electronic device in non-contacting relation, and wherein said electronic device receives and compares said second identification data received from said portable data storage means with said first identification data associated with said operation data received from said data preparation means, and said electronic device only carries out processing based on the operation data uniquely identified by said first identification data when said second identification data received from said portable data storage means matches with said first identification data, wherein said first identification data is standardized to be prepared in a predetermined data size.
