An electronic card game system and method using NFC or RFID electromagnetic communication, including an initiator having a driving coil, a first card having a secondary coil with a capacitor, and a playing piece having a receiving coil. The initiator and the first card may be placed on a playing surface so that at least a portion of the driving coil and at least a portion of the secondary coil overlap. Similarly, the first card and the playing piece may be placed on a playing surface so that at least a portion of the receiving coil and at least a second portion of the secondary coil overlap. These overlapped coils allow a driving signal initiated at the driving coil to be transmitted through the secondary coil and received by the receiving coil.

In accordance with some embodiments, a game table such an electronic baccarat table may be equipped with one or more detecting components (e.g., an RFID antenna, an NFC antenna or an optical reader) to identify gaming elements placed in a certain area of the game table and determine the status of each such gaming element. A specific type of transaction may be automatically inferred by the game table, without a dealer specifically requesting an initiation of a mode or process for the type of transaction, based on statuses of the gaming elements detected within the area and a current phase or stage of a game event. For example, a Change Transaction may be inferred upon the game table determining that both inventory and non-inventory game elements are present within the area of the table at the same time.

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 chip tray system can include multiple chip tube components. A first chip tube component in the chip tray can include one or more gaming chip storage rows corresponding to a first size of gaming chip. A second chip tube component in the chip tray can include one or more gaming chip storage rows corresponding to a second size of gaming chip. An edge of the first chip tube component can be coupled to an edge of the second chip tube component.

According to the present invention, there is provided a management system that prevents misuse of many game tokens during the operation of casino using card game tables in casino and other card game facilities using card game tables. The management system has a function that previously registers IDs of contemplated game tokens on database, manages IDs of game tokens present on a game table chip tray and a storage together with information on location on database, specifies the game token in the game table chip tray and the storage at predetermined timing, and generates an error signal when the following statuses is noticed: 1) a fact that ID absent on database is newly present and 2) a fact that two or more identical IDs are present.

A chip tray system can include multiple chip tube components. A first chip tube component in the chip tray can include one or more gaming chip storage rows corresponding to a first size of gaming chip. A second chip tube component in the chip tray can include one or more gaming chip storage rows corresponding to a second size of gaming chip. An edge of the first chip tube component can be coupled to an edge of the second chip tube component.

A self-resetting game provided by an interactive physical environment includes a plurality of game components, a room sensor, a control system and an indicator. The plurality of game components are repositionable within a game room provided by the interactive physical environment. The room sensor detects a first positon of at least some of the plurality of game components. The control system receives, from the room sensors, the detected position and selects, responsive to the received position information, one of a plurality of game solutions requiring the plurality of game components to be rearranged into a second position different from the first positon. The indicator detects the selected one of the game solutions.

Improved techniques for identifying objects, such as toy objects, are presented herein. In particular, a play system (e.g., game, doll playset, track set, etc.) includes a probed surface for use in obtaining electrical tomography measurements when toy objects are placed on the probed surface. The play system is configured to analyze the electrical tomography measurements to determine an identity of the toy object placed on the probed surface.

A digitizer system comprises at least one object incorporating an electronic tag configured for radiating at least one modulated signal and at least one second signal; a digitizer sensor configured for detecting the at least one second signal while the object is positioned on or over the digitizer sensor; and circuitry configured for identifying the object based on modulation of the at least one modulated signal and for determining a position of the object on or over the digitizer based on the detected second signal on a portion of the digitizer sensor.

A computer-readable storage medium storing program instructions for conducting a game on a gaming system having a wireless input device for playing an interactive motion-sensitive game using a wireless-compatible game console in which a virtual play environment is represented through one or more computer-animated visual, aural or tactile effects is provided wherein game play is conducted by moving, shaking, twisting, waving or pointing the input device in a particular manner. The input device can include motion-sensitive circuitry and/or command circuitry for generating control signals and/or an effects generator and associated control circuitry to enable the input device to selectively generate at least one visual, aural or tactile effect comprising sound, lighting or vibration. The input device can include a wireless transceiver for providing two-way wireless communication with the wireless-compatible game console. An optional display screen displays short text messages received through wireless communications with the wireless-compatible game console.
