Abstract

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.

First claim

The invention claimed is:

1. A dual chip tray comprising:
a lower tray configured to hold gaming chips with embedded RFID tags;
an upper tray configured to:
hold gaming chips with embedded RFID tags,
be moved between a state in which the upper tray is stacked on top of the lower tray and a state in which an upper surface of the lower tray is open;

an upper RFID antenna configured to read the RFID tags of the gaming chips held in the lower tray;
a lower RFID antenna configured to read the RFID tags of the gaming chips held in the upper tray; and
a gaming table device configured to determine the gaming chips held in the upper tray and the gaming chips held in the lower tray based on results of a reading operation associated with the upper RFID antenna and results of a reading operation associated with the lower RFID antenna,
wherein, while the upper tray is stacked on top of the lower tray, the upper RFID antenna is configured not to read the RFID tags of the gaming chips held in the lower tray and/or the lower RFID antenna is configured not to read the RFID tags of the gaming chips held in the upper tray, and
wherein the gaming table device is configured to determine, separately:
the gaming chips held in the upper tray, and
the gaming chips held in the lower tray.

2. The dual chip tray according to claim 1 , further comprising a limiting means configured to limit electromagnetic waves generated by the upper RFID antenna and/or the lower RFID antenna, such that the upper RFID antenna does not read the RFID tags of the gaming chips held in the lower tray and/or the lower RFID antenna does not read the RFID tags of the gaming chips held in the upper tray.

3. The dual chip tray according to claim 2 , wherein the limiting means is a shield configured to block the electromagnetic waves generated by the upper RFID antenna and/or the lower RFID antenna.

4. The dual chip tray according to claim 2 , wherein the limiting means is a jamming antenna configured to generate electromagnetic waves to partially cancel or weaken the electromagnetic waves generated by the upper RFID antenna and/or the lower RFID antenna.

5. The dual chip tray according to claim 2 , wherein:
the upper RFID antenna is configured to read the RFID tags of the gaming chips held in the upper tray and read the RFID tags of some or all of the gaming chips held in the lower tray,
the limiting means is configured to limit the electromagnetic waves generated by the lower RFID antenna such that the lower RFID antenna does not read the RFID tags of the gaming chips held in the upper tray, and
the gaming table device is configured to separately determine the gaming chips held in the upper tray and the gaming chips held in the lower tray based on a collective relationship between the results of the reading operation associated with the upper RFID antenna and the results of the reading operation associated with the lower RFID antenna.

6. The dual chip tray according to claim 2 , wherein:
the lower RFID antenna is configured to read the RFID tags of the gaming chips held in the lower tray and read the RFID tags of some or all of the gaming chips held in the upper tray,
the limiting means is configured to limit the electromagnetic waves generated by the upper RFID antenna such that the upper RFID antenna does not read the RFID tags of the gaming chips held in the lower tray, and
the gaming table device is configured to separately determine the gaming chips held in the upper tray and the gaming chips held in the lower tray based on a collective relationship between the results of the reading operation associated with the upper RFID antenna and the results of the reading operation associated with the lower RFID antenna.

7. The dual chip tray according to claim 1 , wherein:
the upper RFID antenna is configured to read the RFID tags of the gaming chips held in the upper tray and not to read the RFID tags of the gaming chips held in the lower tray, and
the lower RFID antenna is configured to read the RFID tags of the gaming chips held in the lower tray and not to read the RFID tags of the gaming chips held in the upper tray.

8. A dual chip tray comprising:
a lower tray configured to hold gaming chips with embedded RFID tags;
an upper tray configured to:
hold gaming chips with embedded RFID tags, and
be moved between a state in which the upper tray is stacked on top of the lower tray and a state in which an upper surface of the lower tray is open;

an upper RFID antenna configured to perform a reading operation to read the RFID tags of the gaming chips held in the lower tray; and
a lower RFID antenna configured to perform a reading operation to read the RFID tags of the gaming chips held in the upper tray; and
wherein:
while in the state in which the upper tray is stacked on top of the lower tray:
the upper RFID antenna is configured not to read the RFID tags of the gaming chips held in the lower tray, and/or
the lower RFID antenna is configured not to read the RFID tags of the gaming chips held in the upper tray; and

the upper RFID antenna and the lower RFID antenna are coupled to a gaming table device configured to separately determine:
the gaming chips held in the upper tray, and
the gaming chips held in the lower tray.

9. The dual chip tray according to claim 8 , wherein the upper RFID antenna and the lower RFID antenna are communicatively coupled to the gaming table device.

10. The dual chip tray according to claim 9 , wherein:
the upper RFID antenna is configured to indicate a reading operation result of the upper RFID antenna to the gaming table device, and
the lower RFID antenna is configured to indicate a reading operation result of the lower RFID antenna to the gaming table device.

11. The dual chip tray according to claim 9 , wherein the gaming table device is configured to separately determine:
the gaming chips held in the upper tray based on the reading operation result of the lower RFID antenna, and
the gaming chips held in the lower tray based on the reading operation result of the upper RFID antenna.

12. The dual chip tray according to claim 11 , further comprising the gaming table device.
