Token Issuance Linking for Cross-System Interoperability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transaction systems face challenges in enabling seamless interoperability between different token service providers and transaction systems, leading to complexities in token issuance and processing, especially in facilitating transactions across various payment networks and environments.
Innovation Solution
The implementation of a method that involves generating a link between user representations on different transaction systems, allowing for the determination of whether to issue a payment token based on pre-transaction requests, and managing token issuance and processing to facilitate transactions across multiple payment networks and environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple token service providers and transaction systems operate independently, then each system maintains its own security and control, but interoperability between systems becomes complex and difficult to implement
Solution Approach 1:
The patent introduces a token service provider as an intermediary that issues tokens representing payment accounts. These tokens serve as a universal language that different transaction systems can understand and process, enabling interoperability without requiring direct integration between all systems. The token acts as a mediator that bridges independent systems while maintaining their security boundaries.
Solution Approach 2:
The patent creates a universal token format that can represent different payment account types (credit cards, debit cards, prepaid cards) and can be processed by multiple different transaction systems. This universal token structure allows a single token design to serve multiple functions across diverse payment networks and environments.
2Adaptability or versatility
If token issuance is handled by multiple different service providers, then system flexibility and choice increase, but the complexity of token issuance and processing increases
Solution Approach 1:
The patent establishes a homogeneous token structure that all service providers use to represent payment accounts. Regardless of which service provider issues the token, the token format, validation rules, and processing logic remain consistent across all providers. This standardization reduces complexity by eliminating the need to handle multiple different token formats and issuance protocols.
3Reliability
If tokens are issued for every transaction request, then transaction security and authorization are improved, but processing time and system overhead increase
Solution Approach 1:
The patent implements a pre-transaction request mechanism where the system determines whether a token is needed before the actual transaction occurs. By evaluating the request in advance and only issuing tokens when necessary, the system maintains strong authorization security while avoiding the overhead of token issuance for every single transaction, thus reducing processing time and system overhead.

AI summary
The method comprises receiving an onboarding request for a first onboarding process of a first representation of a first user at a token issuance and transaction system, the request received from a transaction system, the request indicating a second onboarding process of a second representation of the first user at the transaction system. The method includes generating, based on performing the first onboarding process and receiving an indication of success of the second onboarding process, a link between the first and second representations at the token issuance and transaction system and the transaction system. The method includes receiving a pre-transaction request from the transaction system, the pre-transaction request indicating a transaction type and the link between the first and second representations. The method also includes determining, based on the link, whether to generate a payment token for completing a requested transaction corresponding to the pre-transaction request.
