Innovation Solution
A credit-card-size device utilizing OLED technology to securely store and display sensitive information, featuring a flexible OLED display that consumes less power, allows for dynamic currency conversion, and includes biometric authentication, enabling secure and efficient financial transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If static anti-counterfeiting properties (special paper or embedded designs) are used on traveler's checks, then counterfeiting protection is improved, but the risk of identification and duplication increases
Solution Approach 1:
The patent replaces static mechanical anti-counterfeiting properties (embedded designs, special paper) with dynamic electronic properties. The EMV chip generates new authorization codes dynamically, and the OLED display can show changing patterns or codes that are difficult to copy, transitioning from static physical security features to dynamic electronic security features.
Solution Approach 2:
The patent changes the security parameters from static (fixed designs, fixed paper characteristics) to dynamic (changing codes, variable display patterns). The EMV chip generates different authorization codes for each transaction, and the OLED display can change its output, making security features adaptive rather than fixed.
2Ease of operation
If sensitive data is printed on the face of credit cards, then ease of operation is improved, but the risk of data exposure and fraud increases
Solution Approach 1:
The patent replaces printed sensitive data with electronic data storage and display. The OLED display can show card information only when needed and in an encrypted or protected manner, eliminating the risk of onlookers copying printed data while maintaining ease of use through electronic presentation.
Solution Approach 2:
The patent makes the display of sensitive data dynamic rather than static. The OLED display can choose when to reveal card information, when to encrypt it, and how to present it, adding a layer of dynamic security that printed data cannot provide.
3Ease of operation
If magnetic stripe encoding is used on credit cards, then ease of operation is improved, but the risk of skimming and data copying increases
Solution Approach 1:
The patent replaces magnetic stripe encoding with electronic encryption and OLED display technology. Sensitive data is not encoded on a physical stripe that can be skimmed, but rather stored securely and displayed only when authenticated, eliminating the skimming vulnerability while maintaining card functionality.
4Adaptability or versatility
If electronic features are added to purchasing instruments, then functionality and security are improved, but device complexity increases
Solution Approach 1:
The patent merges multiple functions into a single integrated system. The EMV chip handles encryption and authentication, the OLED display handles information presentation and dynamic security features, and these components work together as a unified security and functionality system, reducing overall complexity compared to separate systems.
Solution Approach 2:
The patent creates a multi-functional purchasing instrument where the same hardware (EMV chip, OLED display) serves multiple purposes: security authentication, dynamic code generation, information display, and anti-counterfeiting measures, eliminating the need for separate dedicated components for each function.
5Ease of operation
If the form factor is limited to fit in wallet or pocket, then ease of operation is improved, but the difficulty of including electronic features increases
Solution Approach 1:
The patent uses thin-film OLED display technology and flexible electronic components that can be integrated into the card within the standard credit card thickness. The OLED display is a thin film that adds minimal depth, allowing electronic features to be included while maintaining the compact form factor suitable for wallets and pockets.

AI summary
Aspects of the invention relate to a smart check that includes an OLED display. The smart check 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 check may transmit sensitive data associated with the selected purchasing instrument. The smart check may receive power when it is inserted into a card reader. Inserting the smart check into the card reader may launch an application stored on the smart check. The smart check may store a value. The value may be converted into a currency associated with a location of the smart check.
