Secure Card With On-Board Display And Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart cards lack built-in displays for viewing the remaining cash balance, reducing convenience and ease of use in transactions.
Innovation Solution
A secure transaction card with a substrate that includes a display for showing an account identifier only after user authentication, and a communicator that can be activated for account information transmission via magnetic stripe, electrical interface, or wireless RF interface after verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If smart cards use external system power supply through I/O interface, then the card can communicate with external systems, but the card data is only accessible when connected to external system, reducing convenience
Solution Approach 1:
The smart card incorporates an integrated power source (battery) that enables it to operate independently without external power supply. The card can autonomously power its processor, memory, and communication functions, allowing it to perform transactions and access data without requiring connection to an external system for power purposes.
Solution Approach 2:
The smart card integrates multiple functions including power supply, processing, data storage, and communication capabilities into a single device. This multi-functional integration allows the card to operate autonomously while maintaining compatibility with various external systems for different transaction types.
2Ease of operation
If smart cards include built-in displays for viewing cash balance, then user convenience and ease of use improve, but device complexity and manufacturing cost increase
Solution Approach 1:
The display function is integrated directly into the smart card, allowing it to provide balance information autonomously without requiring external display devices. The card's processor controls the display based on data from its memory, enabling self-service information presentation to the user.
Solution Approach 2:
The display component is merged with the card's existing integrated circuit that includes the processor and memory. This combination of display, processing, and storage functions into a single unified system reduces the need for separate external components while maintaining functionality.
3Ease of operation
If smart cards have integrated power source, then card can operate independently improving convenience, but manufacturing complexity and cost increase
Solution Approach 1:
The smart card incorporates an integrated power source (battery) that enables it to operate independently without external power supply. The card can autonomously power its processor, memory, and communication functions, allowing it to perform transactions and access data without requiring connection to an external system for power purposes.
Solution Approach 2:
The card's operational parameters are designed to accommodate the integrated power source, including voltage regulation, power management protocols, and energy consumption optimization. These parameter adjustments enable reliable operation while managing the added complexity of power integration.
Data Source
AI summary
Systems and methods for secure cards with on-board verification are disclosed. In one embodiment, a transaction device associated with at least one transaction account may have a substrate comprising a display that displays an account identifier for the transaction account; a sensor that receives authentication information from a user; a processor that processes the authentication information to verify the authenticity of the user; and a communicator that communicates at least the account information, the communicator including at least one of a magnetic stripe, an electrical interface, and a wireless RF interface. The display may not display the account identifier until the user is authenticated, and the communicator may be inactive to communicate the account information until the user is authenticated.
