Card Shuffling Device with RFID Readers and Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current card shuffling devices do not allow players to see the indicia of the selected card during the shuffling process, lacking the suspense and player engagement provided by other randomizing devices, and they can be inefficient, prone to dealer errors, and require significant dealer involvement.
Innovation Solution
A card shuffling machine with a rotatable body and slots that display the indicia of each card using RFID readers and displays, allowing players to see the cards as they rotate and minimizing dealer interaction through automated selection and security features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cards are retained in the shuffling device during the shuffle, then the card selection process is secure and random, but the indicia of the cards cannot be seen by players, reducing suspense and engagement
Solution Approach 1:
The patent uses RFID readers to create digital copies of card indicia information and displays these copies on screens visible to players. This allows players to see the card information without exposing the physical cards during shuffling, maintaining security while enhancing engagement.
Solution Approach 2:
The patent introduces RFID readers and display screens as intermediaries between the physical cards and the players. The RFID readers read the card information, and the displays present this information to players, eliminating the need to visually expose the physical cards during shuffling.
2Device complexity
If manual card shuffling and selection is used, then the device is simple, but dealer errors increase and efficiency decreases
Solution Approach 1:
The shuffling device performs card selection and identification automatically using RFID technology. The system reads card indicia, determines outcomes, and communicates results without requiring dealer intervention for these tasks, allowing dealers to focus on customer service and game management.
Solution Approach 2:
The patent replaces manual mechanical card handling with automated RFID reading and electronic display systems. This substitution eliminates manual errors in card identification and selection while improving game speed and dealer efficiency.
3Ease of manufacture
If RFID readers and displays are added to the shuffling device, then player engagement and visibility are improved, but device complexity increases
Solution Approach 1:
The RFID readers are integrated into the existing shuffling device structure, serving both the original shuffling function and the new card identification function. The display system is coordinated with the shuffling mechanism to show card information at relevant moments, combining multiple functions within a unified device architecture.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances player engagement and involvement, reduces dealer errors, improves efficiency, and provides increased security by allowing players to see the card selection process and automating the shuffling and selection process.
Implementation Method 1
Each slot includes a reader associated therewith for obtaining the card indicia information from the card disposed in the respective slot
Data Source
AI summary
A card shuffling machine for a game of chance includes a base portion and a rotatable body in communication with the base portion. The rotatable body portion includes a plurality of slots disposed therein. Each of the plurality of slots is configured to receive a card of the defined set of cards. Each of the cards includes indicia relevant to an outcome of the game of chance. The shuffling machine includes at least one reader associated with one of the plurality of slots and configured to communicate with the card disposed in the one slot to obtain information about the indicia of the card. The card shuffling machine includes a display in communication with the at least one reader for displaying the indicia of the card when the card is in the slot.
