Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transaction cards face issues with security and convenience, as they often require visible authentication methods that are susceptible to unauthorized use and require multiple cards for different functions, leading to resource wastage and security risks.
Innovation Solution
A transaction card equipped with sensors that detect touch sequences for user authentication, allowing multiple users and functions to be managed on a single card without visible input, enhancing security and reducing material and resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If visible authentication methods are used on transaction cards, then user convenience is improved, but security is worsened due to susceptibility to unauthorized use
Solution Approach 1:
The patent extracts the authentication input process from the visible domain by utilizing haptic feedback mechanisms. The authentication occurs through tactile sensations that are imperceptible to external observers, thereby maintaining user convenience while eliminating visual exposure that could lead to unauthorized use.
Solution Approach 2:
The patent introduces haptic feedback as an intermediary between the user and the authentication system. This intermediary translates authentication inputs into tactile sensations, allowing the user to authenticate conveniently while the actual authentication data remains concealed from external observation.
2Adaptability or versatility
If multiple cards are used for different functions, then function versatility is improved, but resource consumption is worsened due to material wastage
Solution Approach 1:
The patent implements a single transaction card capable of performing multiple functions through haptic authentication. By encoding different authentication patterns that trigger different operating modes, the card consolidates what would traditionally require multiple separate cards, thereby reducing material consumption while maintaining full functional versatility.
Solution Approach 2:
The patent merges multiple card functions into a single physical card by combining different authentication sequences with a unified haptic feedback mechanism. This consolidation eliminates the need for multiple separate cards, reducing material wastage while preserving all necessary functions through intelligent pattern recognition.
3Adaptability or versatility
If multiple cards are used for different functions, then function versatility is improved, but security is worsened due to increased security risks
Solution Approach 1:
The patent creates a universal card that handles multiple functions through a single secure haptic authentication system. This eliminates the security vulnerabilities associated with carrying and managing multiple cards, as all functions are protected by the same robust haptic verification mechanism, thereby improving overall security while maintaining versatility.
Solution Approach 2:
The patent extracts the security verification process from external visual observation by using haptic feedback. This extraction ensures that even if multiple functions are accessible on a single card, the authentication mechanism remains concealed and secure, preventing unauthorized use while maintaining full functional access for legitimate users.
4Reliability
If touch sequences are concealed from view, then security is improved by preventing unauthorized use, but device complexity is worsened due to sensor requirements
Solution Approach 1:
The patent replaces complex visual or electronic authentication systems with a haptic feedback mechanism that utilizes tactile sensations. This substitution maintains high security by concealing authentication from view while actually simplifying the device architecture by relying on well-established haptic sensor technology rather than more complex concealment mechanisms.

AI summary
A transaction card receives a first input containing a first touch sequence from a first user and including first touch gestures, determines that the first touch sequence corresponds to a first reference touch sequence associated with the first user, and initiates a first operating mode, associated with the first touch sequence, that is associated with the first user and causes the transaction card to perform a first function. The transaction card receives a second input containing a second touch sequence that is different from the first touch sequence, from a second user and including second touch gestures, and initiates, based on determining that the second touch sequence corresponds to a second reference touch sequence, a second operating mode, associated with the second touch sequence, that is associated with the second user and causes the transaction card to perform a second function that is different from the first function.
