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.

A fraud detection system which detects fraud in a game of performing collection and redemption of chips in accordance with a win or lose result includes a camera which captures an image of chips contained in a chip tray of a dealer, an image analyzing apparatus which analyses the image captured by the camera to detect an amount of the chips contained in the chip tray, a card distribution device which determines a win or lose result of a game, and a control device which compares the win or lose result of the game and the amount of the chips contained in the chip tray before and after collection and redemption of the chips to detect fraud.

An inspection system of a chip includes a reading device and a determining unit. The reading device is configured to count a number of chips stored in a storage case, the chips associated with a table game and including a chip having a radio tag, read the radio tag while the chips are stored in the storage case, and acquire chip information. The determining unit is configured to compare the chip information of the chips in the storage case with a physical number of the chips in the storage case, determine that there is an abnormal chips among the chips stored in the storage case based on a determination that the counted number of the chips does not match a physical number of the chips in the storage case, and output a result associated with an indication of the abnormal chip.

Card handling devices may include one or more features for detecting a deficiency relating to at least one card. Methods of operating a card handling device may include detecting a deficiency relating to at least one card.

An automatic card shuffler to shuffle eight decks of cards (or less) and deal a round of Baccarat. The automatic shuffler comprises two pre-shuffle bins, each receiving approximately four decks of cards wherein the pre-shuffle bins are spaced apart from one another with card slides directing to a card-receiving area. Cards are randomly selected from the cards in each of the pre-shuffle bins and propelled onto the card slides directing the cards to the card-receiving area. Once a sufficient number of buffer cards (e.g., seven) have been deposited into the card-receiving area, a card flipper moves the seven cards against a face plate of an integral dealing shoe. A buffer-holder member maintains the buffer cards against the face plate for dealing as the card flipper returns to a home position to receive more shuffled cards while buffer cards are being dealt in a round of Baccarat.

An automatic playing card shuffler system including an automatic playing card shuffler and deck of modified playing cards. The modifications relate to asymmetrical information on each card face, back and/or side for identifying playing card orientation. The asymmetrical information is discernable by one or more image-capturing and/or sensors associated with the automatic playing card shuffler. Accordingly, the orientation of the playing cards may be monitored by the automatic playing card shuffler. The orientation data can be analyzed by a processor of the automatic playing card shuffler to determine unusual orientation patterns indicative of advantage play or cheats. Another version utilizes two distinct marks to identify important cards and less important cards.

An application can be executed for multiple peers using a peer-to-peer network structure. State data for the peers can be compared to provide for authority on the session even though there is no dedicated authority component. Such an approach can help to maintain consistency across the distributed network, as well as to minimize the occurrence of cheating or manipulation of the data on the session. A set of state variables is selected, and peers use their local values for those variables to generate hashes to be sent to the other peers. The hash values are compared and any variations addressed accordingly. For any outlier peers that report different hash values, their state values can be adjusted to attempt to bring those outliers back in sync with the other peers. This can involve updating or rolling back specific parameter values for the outlier or all peers.

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.

A security-enhanced document includes a substrate and variable indicia comprising ink having a signal. The variable indicia is of a specific type and is applied to the substrate using a specific application technique. At least one other printed portion, which is a back of the document, has background ink noise, and the type of ink of the back of the document is of the same type of ink applied to the substrate using the same application technique as the ink of the variable indicia. The document also includes a scratch-off-coating applied over the variable indicia. The document has a signal-to-noise ratio of the ink of the variable indicia relative to the background ink noise of the back of the document that is not appreciable, thereby making the variable indicia unreadable with reference to the back of the document when the scratch-off-coating remains intact.
