Token Vault Mediator for Digital Wallet Provisioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Issuing banks face challenges in seamlessly integrating with third-party digital wallet providers on mobile platforms to extend benefits to their customers, as existing systems lack efficient methods for token linking and unlinking.
Innovation Solution
The method involves an issuer wallet application requesting and provisioning eligible customer accounts to a third-party wallet, linking tokens between the issuer and third-party wallets, and updating token characteristics to ensure seamless transaction processing, using push-provisioning and in-application provisioning techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If issuing banks integrate with third-party digital wallet providers to extend benefits to customers, then customer service capability and market reach are improved, but system complexity and integration difficulty increase
Solution Approach 1:
The patent introduces a token vault as an intermediary component that manages token provisioning and linking between issuer wallet applications and third-party wallet applications. This mediator handles the complex integration logic, allowing issuing banks to extend benefits through third-party wallets without directly managing the integration complexity themselves.
Solution Approach 2:
The system segments the digital wallet ecosystem into distinct functional components: issuer wallet applications, third-party wallet applications, and a centralized token vault. This segmentation allows each component to operate independently with well-defined interfaces, reducing overall system integration complexity while maintaining versatility.
2Adaptability or versatility
If manual token linking processes are used between issuer and third-party wallets, then integration flexibility is maintained, but processing time and operational overhead increase
Solution Approach 1:
The token vault pre-provisions tokens for customer accounts before they are needed in third-party wallet applications. This preliminary action eliminates the need for time-consuming manual token linking processes at the point of use, while the token vault maintains flexibility to link tokens to specific wallets when required.
Solution Approach 2:
The system implements automated self-service mechanisms where the token vault automatically provisions and links tokens between issuer and third-party wallet applications without requiring manual intervention. This reduces processing time while maintaining integration flexibility through programmatic control.
3Adaptability or versatility
If comprehensive token provisioning is implemented across multiple third-party wallets, then customer benefit coverage is improved, but security risks and management complexity increase
Solution Approach 1:
The token vault serves as a secure intermediary that centralizes token management and provisioning. It implements security controls and authentication mechanisms to manage tokens across multiple third-party wallet applications, allowing comprehensive benefit coverage while maintaining centralized security oversight and reducing security risks associated with distributed token management.

AI summary
Systems and methods for token linking and unlinking in digital wallets are disclosed. In one embodiment, a method for token linking in digital wallets may include: an issuer wallet application executed by the information processing device requesting, from a token vault, an identification of a customer's accounts that are eligible for push-provisioning to a third party wallet application executed by the information processing device; receiving the identification of customer accounts from the token vault; identifying accounts provisioned in the third party wallet application; determining accounts from the customer accounts that have not been provisioned to the third party wallet application to provision to the third party wallet application; provisioning the determined accounts to the third party wallet application; and requesting the token vault link a token associated with the provisioned account to an issuer wallet associated with the issuer wallet application.
