Enhanced gaming chips and table game security
First Claim
1. A gaming system comprising:
- a gaming table having a chip tray and an upper surface including a number of gaming chip placement areas;
a plurality of gaming chips placeable within the chip tray, at least one of said plurality of gaming chips containing a plurality of RFID tags wherein at least one of the RFID tags is adapted to transmit data using at least one encryption protocol; and
a plurality of RFID reading devices distributed about the gaming table, each adapted to read data transmitted from one or more of the gaming chips located at the upper surface of the gaming table;
wherein at least one of the plurality of RFID tags includes at least one tamper proof RFID tag having a security breach component that automatically makes an alteration of data stored on the tamper proof RFID tag when an external source makes an unauthorized attempt to write data to the tamper proof RFID tag, said alteration comprising at least one of recording an alert on the RFID tag and erasing at least some of the data from the RFID tag.

Abstract
Systems and methods for tracking RFID gaming chips at a gaming table are disclosed. Gaming chips include an outer body with center and rim portions, and a plurality of RFID tags contained within the outer body. Signals from gaming chip RFID tags can be encrypted only for readers having an appropriate private key, and can be subject to a variable time delay unique to each RFID tag. Separate RFID tags within one gaming chip can be identical for security purposes, and to increase “visibility” to associated RFID readers at the gaming table. Security breach components within RFID tags can reduce or prevent unauthorized writing or tampering attempts to an RFID gaming chip. Further system components include a gaming table and a plurality of RFID reading devices distributed thereabout, including transponders and antennae. Such RFID reading devices are disposed beneath an upper surface of the gaming table in a grid-like fashion.

11. A method comprising:
-
receiving, at a first RFID gaming chip, an interrogation signal from an RFID reading device located at a gaming table during or immediately following a transaction between a host gaming establishment and a patron, said transaction occurring at the gaming table and involving the first RFID gaming chip, said first RFID gaming chip being one of a plurality of RFID gaming chips; transmitting, in response to said interrogation signal, at least two separate answer signals, respectively from two separate RFID tags contained within the first RFID gaming chip; wherein the first RFID gaming chip includes at least one tamper proof RFID tag having a security breach component that automatically makes an alteration of data stored on at least one of the two separate RFID tags when an external source makes an unauthorized attempt to write data to the tamper proof RFID tag, said alteration comprising at least one of recording an alert on the RFID tag, and erasing at least some of the data from the RFID tag. - View Dependent Claims (12, 13)

14. A gaming chip comprising:
-
a center portion, a rim portion, and a specific monetary denomination and amount designated on an outer surface thereof; and a plurality of RFID tags contained within the gaming chip, each of the RFID tags adapted to provide an answer signal in response to an interrogation signal from an RFID source; wherein at least one of the RFID tags comprises a tamper proof RFID tag having a security breach component that automatically makes an alteration of data stored on at least one of the RFID tags when an external source makes an unauthorized attempt to write data to the tamper proof RFID tag, said alteration comprising at least one of recording an alert on the at least one RFID tag and erasing at least some of the data from the at least one RFID tag. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)

22. A gaming chip comprising:
-
a center portion, a rim portion, and a specific monetary denomination and amount designated on an outer surface thereof; and one or more RFID tags contained within the gaming chip, at least one of the RFID tags adapted to provide an intentionally delayed answer signal in response to an interrogation signal from an RFID source, and at least one of the RFID tags being a tamper proof RFID tag that automatically makes an alteration of data stored on the tamper proof RFID tag when an external source makes an unauthorized attempt to write data to one or more of the RFID tags, said alteration comprising at least one of recording an alert on the RFID tag and erasing at least some of the data from the RFID tag.
