Gesture-Based Transaction Card Preauthorization and Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transaction cards lack features to enhance user control and security, particularly in preventing fraud and facilitating secure sharing among users.
Innovation Solution
The system utilizes gesture-based transaction cards that require preauthorization, allowing users to unlock the card for transactions via a mobile device and change authorization conditions dynamically using gestures, while also enabling the sharing of virtual cards securely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If transaction cards store account information for payments, then payment functionality is enabled, but security risks increase due to theft and fraud
Solution Approach 1:
The patent extracts the account information from the physical card by implementing a virtual card system. The virtual card stores account information securely in a mobile device's secure element, while the physical card only contains a token or identifier. This separation allows the physical card to be used for payments without exposing sensitive account information, thereby enabling payment functionality while reducing security risks.
Solution Approach 2:
The patent introduces a token as an intermediary between the physical card and the actual account information. The token serves as a mediator that can be used for transactions without revealing the underlying account details. This intermediary layer protects against theft and fraud while maintaining payment functionality, as the token can be independently managed and revoked without affecting the primary account.
2Adaptability or versatility
If transaction cards share account information with others, then sharing capability is enabled, but security risks increase due to exposure of account information
Solution Approach 1:
The patent segments the card information into multiple components: the primary account information remains secure in the user's mobile device, while shareable virtual card tokens are generated separately. These virtual tokens can be distributed to others without exposing the primary account information. This segmentation enables sharing capability while protecting security by ensuring that even if virtual tokens are compromised, the primary account information remains protected.
Solution Approach 2:
The patent creates virtual copies of card information that can be shared without exposing the original account details. These virtual card tokens are copies that function independently for transactions but contain no sensitive information from the primary account. This copying approach enables sharing capability while maintaining security, as the copies can be revoked or limited without affecting the original account.
3Ease of operation
If transaction cards are always unlocked for use, then ease of use is improved, but security risks increase from unauthorized transactions
Solution Approach 1:
The patent implements preliminary authorization actions through biometric authentication or passcode verification before the card becomes active for transactions. The card remains in a locked state until the user provides proper authentication, at which point the card is temporarily unlocked for use. This preliminary action ensures that only authorized users can activate the card, preventing unauthorized transactions while maintaining ease of use through quick authentication methods.
Solution Approach 2:
The patent makes the card's authorization state dynamic rather than static. The card automatically transitions between locked and unlocked states based on authentication events and transaction completion. After each transaction or after a predetermined time period, the card automatically re-locks, requiring authentication again for subsequent use. This dynamic behavior balances ease of use during active transactions with security when the card is not in use.

AI summary
Disclosed embodiments may include systems and methods for utilizing gesture-based transaction cards. Examples include: first, using a mobile device to preauthorize transaction cards to enter an unlocked state before making a purchase by making a gesture with the transaction card toward the mobile device. Second, using a first transaction card to change an authorization condition of a second transaction card associated with the same account by making a gesture from the first transaction card to the second transaction card. Third, using a first transaction card to distribute a predebited virtual card to the user device of a second user by making a gesture from the first transaction card to the user device of the second user. Additionally, the primary user may be able to upload new authorization conditions to the transaction card and control the system through a related mobile application on a connected mobile device.
