Flexible OLED Smart Card for Secure Payment Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional payment instruments and identification cards have limitations in incorporating electronic security features due to their form factor, making them vulnerable to data exposure and fraud, while also occupying space in users' pockets.
Innovation Solution
A smart card utilizing organic light-emitting diode (OLED) technology that securely stores sensitive data electronically, is flexible, and can be folded or bent, featuring a touch-sensitive OLED display, biometric sensors, and encryption to protect data and enhance security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional payment instruments use printed sensitive data, then the form factor remains simple and compact, but security is compromised due to visible data exposure
Solution Approach 1:
The patent replaces the mechanical/printing system (printed sensitive data on card surface) with an electronic/optical system (OLED display that electronically presents data). The OLED display can show sensitive data only when needed and can be controlled to enhance security, eliminating the permanent visible exposure of printed data while maintaining the compact card form factor.
Solution Approach 2:
The patent changes the state of data presentation from static (printed) to dynamic (electronically controllable). The OLED display allows data to be presented or hidden based on operational parameters, providing security control over when and how sensitive information is exposed, thus improving reliability without significantly increasing device complexity.
2Adaptability or versatility
If multiple identification cards are carried in a wallet, then various identification needs are met, but the number of items in the pocket increases
Solution Approach 1:
The patent implements a single payment instrument that can store and present multiple different identification data sets (credit card data, debit card data, etc.) on one card through the OLED display. This multi-functional approach allows the user to replace multiple physical cards with a single versatile card, reducing the quantity of items carried while maintaining all necessary identification functionalities.
Solution Approach 2:
The patent embeds multiple identification data sets within a single card structure. The OLED display can present different data sets nested within the same physical card, allowing one card to contain the functionality of multiple cards, thus reducing the number of separate items needed.
3Reliability
If electronic features are integrated into payment instruments, then security is enhanced, but the form factor becomes more complex and rigid
Solution Approach 1:
The patent uses a flexible OLED display technology that can be integrated into the thin, flexible structure of a standard payment card. The OLED display and associated electronic components are implemented using flexible substrates and thin-film technologies, allowing the card to maintain its flexibility and ability to be folded or bent while incorporating enhanced security features.
