Solution Overview
Problem
Current gaming systems face challenges in providing secure, efficient, and user-friendly methods for transactions and player tracking, particularly in ensuring privacy and security while allowing easy movement of funds and rewards across different gaming activities.
Innovation Solution
The introduction of photonic-powered card devices that utilize optical communication interfaces, such as IrDA compatible interfaces, to enable secure transactions and communication with gaming machines, where the photonic power source activates a photovoltaic cell on the card for power and only allows data transmission when the card is properly aligned and powered, enhancing security and privacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If contactless card technology is used for transactions, then ease of operation is improved, but security is worsened due to potential unauthorized access
Solution Approach 1:
The patent introduces an optical communication interface as an intermediary between the gaming machine and the card device. This interface requires line-of-sight alignment and optical signaling, creating a physical intermediary that prevents unauthorized contactless access while maintaining ease of operation for authenticated transactions
Solution Approach 2:
The patent replaces traditional magnetic stripe or RFID contactless interfaces with an optical communication system. This substitution uses light-based communication (LEDs and photodetectors) instead of electromagnetic fields or mechanical contact, enhancing security through directional alignment requirements while preserving user-friendly operation
2Device complexity
If photonic power source is used to power the card, then device complexity is reduced, but reliability is worsened due to alignment requirements
Solution Approach 1:
The patent combines the power transfer and data communication functions into a single optical interface. The photonic power source simultaneously provides power to the card device and establishes the authenticated connection, merging two functions into one unified system that reduces overall complexity
Solution Approach 2:
The optical interface serves multiple functions: it provides power to the card device, enables data communication, and establishes authentication. This multi-functionality reduces the need for separate power and communication systems, simplifying the overall device architecture while maintaining reliable operation
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
This solution enables secure, efficient, and user-friendly transactions and player tracking by ensuring that data is only transmitted when the card is properly aligned and powered, reducing the risk of unauthorized access and improving the overall gaming experience.
Implementation Method 1
Each of the portable card devices may include a photovoltaic cell that is configured to provide power for a logic device on the card
Implementation Method 2
The gaming machines may be operable to provide wagering on an outcome of a game of chance, display the outcome of the game of chance, accept cash or an indicia of credit and dispense an award
Data Source
AI summary
A gaming system that is compatible with photonic-powered card devices is described. The gaming system may comprise a number of host devices each coupled to one or more gaming machines. The gaming machines may be operable to provide wagering on an outcome of a game of chance, display the outcome of the game of chance, accept cash or an indicia of credit and dispense an award, such as cash or indicia of credit, to a player utilizing the gaming machine. The gaming machines may be configured to accommodate a photonic-powered card including communicating with these cards via an optical communication interface. One or more transactions on the gaming machine, such as a transfer of cash or indicia of credit on or off the gaming machine or an initiation of a player tracking session, may be enabled using photonic-powered card devices and associated hardware/software.
