Card Shoe Deck Traceability Using Barcode and Lid Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional card shuffling devices fail to identify the shuffled playing card set currently in use, making it difficult to investigate issues with the card shoe apparatus or irregular card insertion, which hampers the ability to take countermeasures.
Innovation Solution
A table game system with a card shoe apparatus that includes a barcode reader to identify uniquely identifiable shuffled playing cards, a control unit to store and track card events, and a display unit to output game results, enabling the system to identify the current card set and record any irregularities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cut card is inserted to prevent card counting, then game security is improved, but the ability to identify the current card set is lost when cards are replaced
Solution Approach 1:
A barcode is attached to the card shoe apparatus before the card set is inserted. This barcode contains identification information that is read by a barcode reader upon insertion, establishing the card set identity before any games are played. This preliminary action ensures that even when cut cards are used and card sets are replaced, the system can identify which card set is currently in use.
2Reliability
If card sets are frequently replaced to maintain game integrity, then game fairness is improved, but the ability to trace and investigate issues is worsened
Solution Approach 1:
The control unit stores the barcode identification information in association with game result information and card distribution information. This creates a feedback mechanism where every card set usage is recorded and traceable. When issues arise, the system can retrieve the specific card set identification and related game data to investigate the cause, maintaining both game fairness through replacement and the ability to trace issues.
3Adaptability or versatility
If manual card dealing is used to maintain game authenticity, then game tradition is preserved, but the ability to detect irregular card insertion is worsened
Solution Approach 1:
A sensor is installed in the card shoe apparatus to detect whether a card has been inserted or removed. This sensor acts as an intermediary between the manual card dealing process and the control system. When the sensor detects irregular card insertion or removal, it triggers an alarm, allowing manual dealing to be maintained for authenticity while automatically detecting irregularities.

AI summary
A table game system is provided capable of identifying shuffled playing cards used at the time of the occurrence of a problem in a card shoe apparatus, thereby enabling an investigation of the cause thereof or the taking of countermeasures therefor. A card shoe apparatus of the table game system of the present invention includes a barcode reader that reads a barcode provided in a shuffled playing card set, thereby reading a shuffled card ID that uniquely identifies the shuffled playing card set. A sensor for detecting the opening/closing of the lid is provided under the lid to detect the opening/closing of the lid, thereby detecting replacement of the shuffled playing card set. A control unit further includes a function of storing security items in connection with a shuffled card ID.
