    Abstract: PROBLEM TO BE SOLVED: To provide RF powder particles, RF powder, and a substrate containing the RF powder, which make it difficult to produce forged documents, forged bank notes, etc. with respect to sheet-like objects having high property value such as bank notes and allow required information to be stored respectively in many particles each of which is provided with one tank circuit having a prescribed resonance frequency. SOLUTION: An RF powder particle has a coil 24 (inductance element) as a magnetic field coupling element and a capacitor 25 (capacitance element) connected to both ends of the coil, formed on an insulating surface of a substrate 22 and is configured so as to form a tank circuit 31 by the inductance element and the capacitance element. The tank circuit 31 functions as a circuit in a resonance state or a circuit in a non-resonance circuit in accordance with a condition in response to a high-frequency magnetic field given from the outside.

    Abstract: PROBLEM TO BE SOLVED: To provide a function for checking whether an IC card is altered, especially easily check whether a description content on a front surface is replaced. SOLUTION: The IC card for describing record information such as personal information and having an optical change element image on a side of the front surface, stores characteristic information of the optical change element image together with the record information of such as the personal information in a memory inside. In addition, authenticity is determined by comparing the characteristic information of the optical change element image placed on a card front surface and the characteristic information stored in the memory in the inside of the IC card, and access to other stored information in the inside of the memory is permitted.
