Biometric E-Wallet Authentication for Cashless Gaming Transactions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current gaming machines and financial services kiosks face inefficiencies in cash handling, requiring manual interaction and multiple forms of payment, which can complicate transactions and user experience.
Innovation Solution
Implementing a biometric user recognition system integrated with a single electronic wallet environment, allowing users to manage accounts and make transactions seamlessly through a network-connected gaming or financial services server, using biometric devices and payment devices for secure and convenient cashless operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If biometric authentication is implemented with automatic e-wallet integration, then user convenience and transaction speed are improved, but system complexity and security requirements increase
Solution Approach 1:
The system enables users to automatically authenticate and access their e-wallet funds through biometric recognition without requiring manual intervention, account selection, or complex navigation. The biometric device directly triggers fund transfers, allowing the system to serve itself by automatically completing transactions based on biometric verification alone.
Solution Approach 2:
The biometric authentication system serves multiple functions: it authenticates user identity, unlocks the e-wallet account, authorizes fund transfers, and integrates with both conventional payment devices and electronic money systems. This single biometric interface replaces multiple authentication methods and simplifies the user experience while handling diverse transaction types.
2Adaptability or versatility
If a single electronic wallet environment is used for both conventional and electronic payments, then transaction versatility is improved, but security requirements and system complexity increase
Solution Approach 1:
The system introduces a centralized e-wallet account as an intermediary layer between conventional payment devices and electronic money systems. This single e-wallet environment acts as a mediator that can receive funds from various sources (cash, card, electronic transfer) and disburse to multiple destinations, providing versatile transaction capabilities while maintaining a unified security framework through biometric authentication.
3Reliability
If biometric devices are locked during payment operations, then security is improved, but user access flexibility is reduced
Solution Approach 1:
The biometric device operates in periodic cycles: it is locked during payment operations to prevent unauthorized access, then unlocked for a limited time window to allow legitimate users to access their e-wallet, and re-locked afterward. This periodic locking and unlocking pattern maintains security while providing necessary user access flexibility within controlled time frames.
