  The present invention relates to an authentication determination device, and more specifically, electromagnetically couples at least one movable handy antenna to one reader, and determines whether or not the ID of an IC card read by the handy antenna is authenticated. The present invention relates to an authentication determination device.

Conventionally, in event venues and paid facilities, handy cards placed at gates when entering and entering ID information for identifying visitors, venue names, and data such as date and time of entry are entered. A staff member with a reader reads the data recorded in the admission ticket etc. and determines whether the admission ticket etc. is genuine on the spot. However, the handy reader is equipped with a reading unit that reads data such as admission tickets, a control unit that determines whether the read data is legitimate content, a battery that supplies power, etc. It is a heavy object that is a heavy burden when gripping and operating with one hand, and the operator is easily fatigued. In addition, since the cost is not cheap, there is a problem that the operation cost increases by providing handy leaders to many staff members.
As a conventional technique, Patent Document 1 includes a handy reader that reads information attached to a product, a memory that stores the read information, a display unit, and a communication unit. A product information display system is disclosed that utilizes the contents of the memory as information storage contents and can be easily displayed by a reader / writer without being connected to a network.
