Abstract: A property management system includes: a management server for managing a property item by a non-contact IC medium; a gate apparatus for reading medium information from the non-contact IC medium; and a destruction apparatus for destroying the property item. Gate passage permission/non-permission information is stored on the management server or the non-contact IC medium and, when destroying the property item, the destruction apparatus transmits the medium information to the management server to perform a destruction completion registration. The gate apparatus includes: a determination device for determining whether the gate passage permission/non-permission information represents permission or non-permission based on the medium information; and a passage prohibition device for prohibiting passage when the determination result is non-permission.

Abstract: A container for preventing stealage of information recorded in a medium such as a card and compatible with security check conducted by X-rays at an airport or the like. A portable pouch is of a bag-like shape and produced by base clothes, on which a laminated film is laminated. The laminated film is a film including an aluminum foil layer and a resin layer laminated on each other. The aluminum foil layer is set up to have a thickness so as to transmit X-rays and an electromagnetic wave of an extremely high-frequency range and to shield an electromagnetic wave of a high-frequency range. The protection film shields an electromagnetic wave generated from a card and prevents leakage of the electromagnetic wave, thereby avoiding skimming. Further, the protection film transmits X-rays, thereby being compatible with X-ray check at an airport or the like.

Abstract: A magnetic data eraser includes a power supply circuit, a receptacle for accommodating a magnetic recording medium or a device incorporating a magnetic recording medium, primary and secondary coils wound around an outer periphery of the receptacle. The primary coil is connected to the power supply circuit. The secondary coil is short-circuited. Excitation of the primary coil through energization by the power supply circuit generates an induced current in the secondary coil, thereby making an interaction between the primary and secondary coils. The interaction generates an alternating magnetic field, whereby the magnetic recording medium is degaussed, so as to erase magnetic data recorded in the medium.
