PROBLEM TO BE SOLVED: To provide a code data writing device for cumulatively writing the status of an object at a prescribed time or place in a storage medium given to the object, as a code data.SOLUTION: The code data system 1 includes code data writing devices 10 (a, b and c) and data storage devices 30 (a, b and c). The code data writing systems 10 are connected to the data storage devices 30 via a communication network 40. The code data writing systems 10 write a code data in a storage medium 22 given to an object 20 located in the process of circulation. At this time, the code data writing devices 10 may write information obtained from the data storage devices 30 via the communication network 40 or a code data containing information for obtaining information possessed by the data storage devices 30, in the storage medium 22. |
