OLED Smart Card Integrating Biometric Sensors for Secure Data Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current credit cards face challenges in securely protecting sensitive data due to their limited form factor, which restricts the incorporation of electronic features that could enhance security and functionality, while existing fraud prevention technologies like EMV chips have limitations in design and usability.
Innovation Solution
The integration of organic light-emitting diode (OLED) technology into credit-card-size devices to create smart cards that store sensitive data electronically, featuring a touch-sensitive OLED display, biometric sensors, and communication circuits, allowing secure data management, authentication, and enhanced functionality without increasing the card's thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electronic features are incorporated into credit-card-size devices to enhance security and functionality, then security and functionality are improved, but device complexity increases
Solution Approach 1:
The patent merges multiple functional components (OLED display, biometric sensors, communication circuits, power supply) into a single integrated smart card device, combining security, display, authentication, and communication functions in one compact unit that maintains credit-card dimensions
Solution Approach 2:
The smart card is designed as a multi-functional device that serves as both a traditional payment instrument and an electronic display device with biometric authentication capabilities, replacing multiple separate devices (credit card, ID card, authentication device) with a single universal card
2Adaptability or versatility
If electronic features are incorporated into credit-card-size devices, then functionality is enhanced, but the form factor constraints are worsened
Solution Approach 1:
The patent utilizes the third dimension (thickness) efficiently by implementing a layered structure where the OLED display, sensors, and circuits are stacked vertically, allowing full functionality within the constrained credit-card thickness while maintaining standard card dimensions
3Ease of operation
If sensitive data is printed on the face of the credit card for easy access, then ease of operation is improved, but security is worsened due to visibility to onlookers
Solution Approach 1:
The patent extracts sensitive data from the visible printed format and stores it electronically within the card's secure memory, removing the data from public view while maintaining easy electronic access through the OLED display and biometric authentication system
Solution Approach 2:
The OLED display enables dynamic visual presentation of card information, allowing the card to display different data (including sensitive information) only when activated and authenticated, rather than having static visible printing that is always exposed
4Object-affected harmful factors
If sensitive data is encoded on a magnetic stripe for secure storage, then security is improved, but ease of operation is worsened due to skimming device vulnerabilities
Solution Approach 1:
The patent introduces an intermediary authentication layer (biometric sensors and OLED display) between the user and the sensitive data, requiring active user verification before data access, thereby preventing unauthorized skimming while maintaining legitimate user access

AI summary
Aspects of the invention relate to a smart card that includes an OLED display. The smart card may store data associated with multiple purchasing instruments and utilize the OLED display to present sensitive data associated with a user selected purchasing instrument. In response to the selection, the smart card may transmit sensitive data associated with the selected purchasing instrument. The OLED display may allow the smart card to include a customizable face. The OLED display may present video, colors or any suitable text. For example, the OLED display may present a user's credit limit, rewards or spend categories. Such smart cards may be easily re-branded as a result of the smart card not being permanently tied to an embossed number. New sensitive data may be pushed to the smart card and thereby allow it to be used immediately based on the new sensitive data.
