When an unfair gaming currency is delivered to a dealer from a player, the currency is detected as unfair. The inspection system for inspecting the gaming currency, in which an RF tag is built, comprises: a gaming currency tray for housing the gaming currencies of the dealer in a casino game; an RF reader for reading the RF tags of the plural gaming currencies housed in the gaming currency tray; plural photosensors for detecting at least the number of the plural gaming currencies housed in the gaming currency tray at a constant time interval or always in a method other than RFID; and an inspection/alarm part for generating alarms when the number of the gaming currencies whose RF tags are read by the RF reader is not equal to the number of the gaming currencies detected by the plural photosensors.

An inspection system inspects gaming chips each having a color or a display indicating a value on an outer surface in a state where the gaming chips are stored in a case in which a maximum of the number of gaming chips to be stored is limited, and a radio tag storing gaming chip information is embedded in each of the gaming chips. The gaming chips are stored in the case capable of containing a row of gaming chips stacked in a thickness direction, and the inspection system includes a reading device that reads the radio tag of the gaming chip in the case and acquires gaming chip information of the gaming chip and a determining unit that compares the gaming chip information with a maximum of the number of gaming chips storable in the case and determines an abnormality of the gaming chip in the case when the number of gaming chips obtained from the gaming chip information is different from a maximum of the number of storable gaming chips.

A system for verifying authenticity of precious metal coins and bars includes a sensor system defining a sample region configured to receive a precious metal coin or bar therein; a sample support; and a data processor configured to communicate with the sensor system so as to receive a detection signal therefrom and to provide an output signal. The system includes a data storage device and an output display. The sensor system detects a bulk electrical property of the coin or bar. The data processor processes the detection signal and retrieves a stored physical property from the data storage device to provide an output signal that includes at least a measured value of the bulk electrical property and a corresponding range of expected values. The output display uses the output signal to display information for a user to be able to make an authenticity verification of the coin or bar.

Throughout the world, there is growing trend by investors to protect wealth by holding silver and gold coins and bars. Unfortunately, there are also a growing number of counterfeit coins and bars coming into in circulation. This situation cries out for an affordable method that can be used by untrained investors to quickly and reliably discriminate authentic coins and bars from counterfeit ones without causing damage to their coins and bars. The disclosed method fills this need by the use of a combination of conventional and novel designed pieces of equipment for measuring the following three characteristics of a coin; (1) size, (2) weight, and (3) relative terminal velocity on a magnetic slide. The results of these measurements can be used to unambiguously discriminate pure silver and pure gold investment coins and bars from counterfeit ones and can also be helpful in evaluating 22-karat gold coins and pure platinum coins.

Provided is an inspection system that uses RFIDs to inspect articles such as valuables, and is capable of detecting that articles are present with an RF tag that cannot be read. An inspection system where products (9) with types capable of being specified by a weight difference are set as an inspection target, the inspection system for inspecting the products (9) provided with RF tags (8) on which information of the products (9) is recorded, and provided with: an RF reading device (1) for reading the information of the products (9) from the RF tags (8) of the products (9) placed on a placement platform (22); a weight measuring device (2) for measuring and recording weights of the products (9); and a management control device (3) for using measurement results of the weight measuring device (2) to ascertain a total weight of the products (9) on the placement platform (22). The management control device (3) is provided with a function for ascertaining the weights of the products (9) on the placement platform (22) based on standard weights of the products (9) from the information obtained from the RF reading device (1), measuring the total weight of the products (9) on the placement platform (22) by using the measurement results of the weight measuring device (2), performing a comparison between a calculated weight of the products (9) obtained from the RF reading device (1) and a total weight of the products (9) obtained from the measurement results of the weight measuring device (2), and estimating whether or not the totals of the number of the products (9) are matching.
