Definitions

  • the Present invention relates to game tokens, a game verification system and a method.
  • Embodiments of the present invention relates to gaming chips or tokens, and in particular to a method and apparatus for securely verifying the identity of a gaming chip or token.
  • Games of chance have been enjoyed by people for many years and have undergone increased and widespread popularity in recent times. As such, the gaming establishments that offer games of chance frequently deal in large sums of currency that change hands between the establishment and the patrons. Gaming establishments or casinos will commonly provide players with a convenient form in which to facilitate the monetary transactions. Casinos will usually implement some form of gaming chip or token payment scheme to facilitate the monetary transactions. In this type of payment structure, the player will usually obtain a gaming token that has an associated value in exchange for actual currency.
  • the player may desire to obtain $100 worth of gaming tokens where the tokens are each worth $10.
  • the player would provide the actual currency to the gaming establishment; the player would then receive ten $10 gaming tokens in which the player may now use in the gaming establishment for placing wagers on the various games of chance.
  • the player when the player receives a winning payout in a game of chance, the player is typically paid in gaming tokens which may be re-issued. In this way, the gaming tokens become a form of proprietary currency for that gaming establishment. When the player has determined that they no longer desire to participate in the games of chance, the player may "cash-in" or redeem the gaming tokens for actual currency.
  • the gaming chip/token payment scheme has several advantages to the gaming establishment it also brings disadvantages.
  • One disadvantage of the currently used gaming token scheme is that perpetrators attempt to counterfeit the gaming tokens and thus use the impostor tokens to defraud the gaming establishment of revenue.
  • a gaming token with a minimal value i.e. $1
  • the perpetrator then defrauds the gaming establishment by cashing in or betting what was originally only a $1 token for a $1,000.
  • the same high quality manufacturing method that is used to create the original tokens may be used to create counterfeit tokens.
  • Another attempt to provide an anti-counterfeiting measure was to secretly code the gaming token with an external identifier that could easily viewed with the naked eye, or could only be viewed under a specific lighting condition such as illumination by a specific fluorescent black light. While this solution was marginally helpful in preventing counterfeiting, this method was subsequently counterfeited along with the gaming token. Once a perpetrator obtained the specific fluorescent lamp, and matching stamp/ink/paint, all that was required to subvert this method was duplication of the coded external identifier.
  • embodiments seek to provide a gaming token that has an internal redundant system for verifying the token's integrity and associated value in the event the primary transponder fails or external identifier is unreadable.
  • embodiments provide a method and apparatus for gaming token verification comprised of a primary and secondary token identification.
  • a gaming establishment may cross-reference and verify a gaming token's value, origin and integrity.
  • the apparatus includes a game token comprising: a token having a recess formed therein and a carrier substantially received within the recess.

  • the primary and secondary identification elements may be formed on the token.
  • the primary identification element may have game token information encoded therein while the secondary identification element may provide identification information associated with a manifest.
  • the primary identification element may comprise an electronic transponder, such as a radio frequency identification chip, in one or more embodiments.
  • the secondary identification element may be an alphanumeric code, a bar code or both which may or may not be configured to be readable by a device such as a reader.
  • the reader may comprise a radio frequency identification chip reader, an X-ray device or T-ray device.
  • the reader may also be an X-ray imaging device even an X-ray imaging device with a bar code scanner.
  • the game token comprises a token having a recess formed therein, a carrier substantially received within the recess, and at least two identification elements associated with the token.
  • the first identification element may have game token information encoded thereon, while the second identification element may provide identification information associated with a manifest.
  • the first identification element may comprise an electronic transponder, such as a radio frequency identification chip, in one or more embodiments.

  • the reader may be generally capable of accessing the secondary identification element of a game token in one or more embodiments and may be in communication with a computer, the computer configured to access a database, where the database may contain a manifest of game token identification data.
  • Game token data may be displayed to a system operator on a display connected to the computer.
  • a computer program operatively running on the computer may be configured to compare game token data obtained from the reader with game token data within said manifest. This may be used to verify the authenticity of a game token.
  • a method of verifying a game token prior to redeeming it for currency or other value is also provided.
  • the method generally comprises: reading the secondary identification element of a game token to obtain a secondary game token identification; accessing a database containing a list of game token data; locating the secondary game token identification; obtaining a currency value for the game token from a manifest associated with the secondary game token identification; and paying the currency value of the game token if the currency value, as received from the manifest, matches a face value of the game token. If the currency value of the game token does not match the currency value from the manifest, payment of currency value for the game token may be refused.

It is contemplated that each vital step of the game token production process be recorded in the manifest and the responsible party at each step be identified. This provides increased security and the ability to track the production history of the game token 100. This can be used to help identify fraud or theft.
  • step 612 the completed game tokens and associated manifest are securely delivered to the gaming establishment.
  • This delivery comprises both actual physical delivery of the gaming tokens and a transfer of the manifest in some form of secure/authenticated data transfer such as by way of an encrypted CD, DVD, flash memory or by way of secure network download.
  • the gaming establishment After receipt of both the physical game tokens and the electronic manifest, the gaming establishment performs optional inventory intake processing of these items in step 616.
  • the actual physical game tokens are electronically read into a computer system and compared to the electronic data recorded in the manifest.
  • Parameters that may be compared are the primary/secondary transmitted token values, token face value, manifest token values, software version, serial numbers, or any other value, data, or parameter.
  • a game token may be presented for redemption at the gaming establishment.
  • the token's currency value will need to be verified to ensure the game token is not counterfeit.
  • the game token's primary identification may be queried and should provide the correct value of the token. In one embodiment this comprises a visual inspection of the token or RFID read process.
  • the gaming establishment personnel may then compare the actual physical value as shown on the face of the game token with the value transmitted by the primary identification circuit.
  • the personnel may permit redemption of the token, at step 642 if there is confirmation of the value of the game token. Should there be a discrepancy, the game token may require additional processing at a step 638.
  • the detection system of embodiments of the present invention may be initiated to query the secondary game token identification 646.
  • the gaming establishment personnel may either use an alphanumeric serial number, bar code or both to compare with the manifest data. In either event, the gaming establishment personnel will obtain secondary identification and compare this with the manifest data 654. After comparison at step 658, there will either be a confirmation of the secondary information and the manifest data and if so, redemption may be permitted 664. Conversely, if there is no confirmation between the secondary information and the manifest data, the game token may be quarantined 662.
  • the term quarantined as used herein is defined to mean removed from play and optionally investigated.
  • the apparatus and method described herein has numerous advantages over other game token identification innovations. Once such advantage is that embodiments of the present invention provide a gaming establishment with a secondary way to verify a game token's true or intended value. This secondary identification may be implemented when the primary identification means has failed. Thus the gaming establishment has more than one way to verify a game token's value.
  • embodiments of the present invention provide for substantially increased security throughout the entire manufacturing process.
  • a manifest is updated with various pertinent information regarding the game token, in this way a historical document is generated that catalogs the production process. This provides several levels of review and involves personnel from several companies to produce the final game token and associated manifest.
  • a manifest that tracks the actual production of game tokens, the probability of a conspiracy to modify or alter the game tokens is reduced because the conspiracy would require involvement from management personal from several companies and this is unlikely.
  • Yet another advantage of embodiments of the present invention is that inventory intake processing at the gaming establishment is streamlined.
  • the intake process was very labor intensive and required personnel to verify each token. This could be extremely time-consuming in the case where the gaming establishment ordered hundreds or thousands of game tokens.
  • Embodiments of the present invention provide an enhanced system for intake processing and verification of freshly manufactured game tokens.
  • Embodiments provide an apparatus and method for verifying the integrity and correct value of a game token.
  • the token includes a primary and a secondary source of identification.
  • the preferred primary token identification is an embedded RFID tag.
  • the secondary token identification may be an alphanumeric serial number, a bar code or combination thereof.
  • the game token is produced in conjunction with an electronic manifest.
  • the manifest provides a production history of the game tokens and is a source of verification data. The data is subsequently used by a gaming establishment to verify the face value of the game token as compared to the physical appearance of the game token. In this way, counterfeit or altered game tokens may be identified prior to redemption.
