PROBLEM TO BE SOLVED: To provide a virtual ID device whose communication distance is long, and whose extensibility is excellent using a tag whose heat resistance and cost performance is excellent with a simple constitution, and its tag data storing method. SOLUTION: This virtual ID device is provided with a server controller 2, ID controllers I1-In connected to host equipment U1-Un, and tag TA1-TAk,..., TN1-TNk being the targets of detection of the respective ID controllers I1-In, and a tag is constituted only of a tank circuit in which the coil of an inductance Lki being a passive element and the capacitor of an electrostatic capacity Cki are connected in parallel. The identification information and data of the tag are stored in a data storing means 4 of the server controller 2 so that the memory for storing the data of the tag can be physically separated from the tag. |
