1. a RFID information medium, carries out data communication non-contiguously with outside reading device, it is characterized in that,Comprise:

  • There is the main part of insulating component,Be arranged at the surface of described main part across adhesive linkage, the optically variable device that color and image change according to visual observational technique,Be built in the antenna member of described main part;

    Described optically variable device has the reflection horizon of electric conductivity or the hyaline layer of electric conductivity as conductive material layer,This conductive material layer partly overlaps with member with described antenna on the thickness direction of described main part,Described conductive material layer and described antenna member are electrically connected by capacitive coupling on described thickness direction,Described antenna does not have separately antenna function with member, and by bringing into play antenna function with the co-operation of described conductive material layer.
