Payment Intermediary System for External Token Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for network transactions lack an efficient method to securely manage and associate tokens from multiple token service providers with corresponding payment accounts, limiting the ability of payment networks to provide value-added services across transactions.
Innovation Solution
The system integrates an integration engine that pulls and stores tokens from multiple token providers in a vault data structure, allowing payment networks to map tokens to associated payment accounts, even when tokens are generated externally, enabling the provision of value-added services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If tokens are generated externally by multiple token service providers, then token diversity and adaptability are improved, but the ability of payment networks to map tokens to payment accounts deteriorates
Solution Approach 1:
The patent introduces a payment intermediary system that acts as a mediator between external token service providers and the payment network. This intermediary receives tokens from multiple external providers, maintains mappings between tokens and payment accounts, and enables the payment network to process tokenized transactions even though the tokens originate outside the network. The intermediary translates and bridges the gap between external token systems and internal payment processing.
2Ease of operation
If primary account numbers are used for transactions, then transaction processing simplicity is improved, but security deteriorates
Solution Approach 1:
The patent implements tokenization by creating substitute representations (tokens) of primary account numbers. These tokens are generated by token service providers and mapped to the original PANs in the payment intermediary system. The tokens can be used in transactions instead of actual PANs, providing enhanced security while maintaining the ability to process transactions through the payment network infrastructure.

AI summary
Systems and methods are provided for managing tokens from different token providers and facilitating network transactions involving tokens from the different token providers. One exemplary method includes receiving a request to provision a token for a payment account to a party, where the payment account is associated with a payment network. The method also includes generating the requested token apart from the payment network, whereby the requested token is an external token, and transmitting the external token to the party. The method further includes transmitting, to the payment network, the external token and a PAN for the payment account associated with the external token, thereby permitting the payment network to map the token to the PAN and to provide PAN-dependent services for a transaction based on an authorization request message including the token but not the PAN.
