Inspection device for detecting fraud
A detection system including a control device detecting fraud performed in a game table by using a result of an image analysis performed by an image analyzing device is included. A substitute currency for gaming used for this detection system has a multi-layer structure in which a plurality of plastic layers having different colors are stacked, a coloring layer is included at least in the middle, and white layers or thin-color layers (may be layers having a color thinner than that of the coloring layer; not illustrated in the drawing) are stacked on both sides of the coloring layer disposed in the middle.
1. An inspection device for valuable objects (a) whose respective values can be identified by respective external appearances, colors, or dimensions of the valuable objects and (b) including respective radio frequency identifications (RFID) in each of which information of the respective valuable object is recorded, the inspection device comprising:
an RFID reading device, wherein the RFID reading device is configured to read the information of the valuable objects from the RFID when the valuable objects are placed;
a camera device, wherein the camera device is configured to image and record the valuable objects using a camera; and
a management control device, wherein the management control device is configured to:
determine and store a total number of the placed valuable objects by using a result of the imaging performed by the camera device;
determine the total number of the placed valuable objects from information supplied from the RFID reading device; and
identify a mismatch between the total number of the valuable objects determined from information supplied from the RFID reading device and the total number of the valuable objects determined using the result of the imaging performed by the camera device.
2. The inspection device according to claim 1 , wherein the management control device is configured to:
determine the total number of the placed valuable objects respectively for each of a plurality of types of the valuable objects from the information supplied from the RFID reading device;
determine the total number of the placed valuable objects for the each of the plurality of types of the valuable objects using the result of the imaging performed by the camera device; and
identify the mismatch, respectively for each of the plurality of types, between the respective total number of the valuable objects determined for the respective type from the information supplied from the RFID reading device and the respective total number of the valuable objects determined for the respective type using the result of the imaging performed by the camera device.
3. The inspection device according to claim 1 , wherein the management control device is configured to:
determine a total value of the placed valuable objects from the information supplied from the RFID reading device;
determine the total value of the placed valuable objects by using the result of the imaging performed by the camera device; and
identify a mismatch between the total value of the valuable objects determined from the information from the RFID reading device and the total value of the valuable objects determined using the result of the imaging performed by the camera device.
