Abstract

Systems and methods for monitoring shuffled playing cards. A shuffled card ID is associated with the one or more shuffled decks of playing cards. Each card delivered by a card feeder from the one or more shuffled decks of playing cards is inspected. It is determined whether there is a defect in the arrangement of the one or more shuffled decks of playing cards. Upon a condition that a shuffled deck of playing cards is determined to be defective, at least one of discarding the defective shuffled deck of playing cards or preventing a recurrence of a defect found within the defective shuffled deck of playing cards.

Claims

1. A method of inspecting one or more shuffled decks of playing cards, wherein each of the one or more shuffled decks of playing cards are shuffled at random, the method comprising the steps of:

associating, by a process control system having one or more processors, a shuffled card ID with the one or more shuffled decks of playing cards, wherein the shuffled card ID is unique for the one or more shuffled decks of playing cards packaged in an individual package and the shuffled card ID comprises information about a manufacture or delivery of the one or more shuffled decks of playing cards;

inspecting, by at least one of a card sensor and a camera, each card delivered by a card feeder from the one or more shuffled decks of playing cards;

determining whether there is a defect in the arrangement of the one or more shuffled decks of playing cards; and

upon a condition that a shuffled deck of playing cards is determined to be defective, at least one of discarding the defective shuffled deck of playing cards or preventing a recurrence of a defect found within the defective shuffled deck of playing cards.

2. The method according to claim 1, wherein the step of determining whether there is a defect in the arrangement of the one or more shuffled decks of playing cards comprises determining whether there is an excess or deficiency in the number of cards of the one or more shuffled decks of playing cards.

3. The method according to claim 1, wherein the step of determining whether there is a defect in the arrangement of the one or more shuffled decks of playing cards comprises determining whether there is an irregularity in the shuffling of the one or more shuffled decks of playing cards.

4. The method according to claim 3, wherein the irregularity in the shuffling of the one or more shuffled decks of playing cards comprises a number of times at least one kind of card appears in a predetermined number of cards is more than a total number of the shuffled decks of playing cards.

5. The method according to claim 3, wherein an irregularity in the shuffling of the one or more shuffled decks of playing cards comprises determining a relative arrangement of a predetermined number of the cards.

6. The method according to claim 3, wherein upon the detection of the irregularity in shuffling, operating a lock member to restrict movement of the cards.

7. The method of claim 5, wherein the step of determining the relative arrangement comprises determining at least one of a rank or a suit of each of the predetermined number of cards drawn in sequence from a card housing unit.

8. The method according to claim 7, wherein the step of determining the relative arrangement comprises determining whether the ranks of cards increase or decrease in order.

9. The method according to claim 7, wherein the step of determining the relative arrangement comprises determining whether each of the predetermined number of cards have the same rank.

10. The method according to claim 7, wherein the step of determining the relative arrangement comprises determining whether each of the predetermined number of cards are of the same suit.

11. The method according to claim 7, wherein the step of determining the relative arrangement comprises determining whether a repeating sequence of a rank or a suit is present within the predetermined number of cards.

12. The method according to claim 7, wherein the step of determining the relative arrangement comprises determining whether the determined relative arrangement matches a pre-stored relative arrangement.

13. The method according to claim 7, wherein the step of determining the relative arrangement comprises determining whether each of the predetermined number of cards have the same rank and are of the same suit as compared to a corresponding card in a preceding deck of cards in a set.

14. The method according to claim 7, wherein the step of determining the relative arrangement comprises determining whether each of the predetermined number of cards have the same rank and are of the same suit as compared to a corresponding card in a preceding set of cards checked in a previous detection.

15. The method according to claim 7, wherein the step of determining the relative arrangement comprises reading a code on each of the cards that indicates at least one of the rank or the suit of the card.

16. The method according to claim 7, wherein the step of determining the relative arrangement comprises reading an authenticity determination code on each the cards.

17. The method according to claim 15, wherein the step of determining whether there is an irregularity in the shuffling comprises comparing the code with a predetermined code stored in a memory.

18. The method according to claim 16, wherein the step of determining whether there is an irregularity in the shuffling comprises comparing the authenticity determination code on each of the cards with a predetermined authenticity determination code stored in the memory.

19. The method according to claim 1, wherein the step of determining whether there is a defect in the arrangement of the one or more shuffled decks of playing cards comprises determining whether there is a smudge on one of the inspected cards.

20. The method according to claim 1, wherein the step of determining whether there is a defect in the arrangement of the one or more shuffled decks of playing cards comprises determining whether one or more of the inspected cards has been improperly cut.

21. The method according to claim 1, wherein each of the one or more shuffled decks of playing cards is contained within a card shoe apparatus.

22. The method according to claim 1, wherein each of the one or more shuffled decks of playing cards is contained within a corresponding package having a sealing label, and the shuffled card ID associated with the shuffled deck of playing cards is attached to the package.

23. The method according to claim 22, wherein the shuffled card ID is associated with production information of the one or more shuffled decks of playing cards, and the production information is related to identification of a manufacturing line used to shuffle the one or more decks of shuffled playing cards.

24. The method according to claim 22, wherein the shuffled card ID associated with the shuffled deck of playing cards is attached to the sealing label.

25. The method according to claim 22, wherein the shuffled card ID is a bar code, RFID tag, RF tag or a two-dimensional matrix code.

26. The method according to claim 22, wherein the shuffled card ID is further associated with a product type of the shuffled deck of playing cards, shipment information or customer information.

27. The method according to claim 22, wherein each shuffled card ID is registered in a database by associating the shuffled card ID with information related to a shuffling machine or a shuffling machine group used to shuffle the shuffled deck of playing cards to which the shuffled card ID is attached.
