Digital Tag Transfer Application for Secure Payment Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transaction systems face challenges in securely and efficiently exchanging primary account numbers between users, as they often require manual input and involve sharing sensitive personal data like email addresses or phone numbers, which can be inconvenient and raise privacy concerns.
Innovation Solution
A method using digital tags associated with users, where a transfer application receives a payload with a digital tag and transaction amount, transmits the digital tag to a digital tag computer, retrieves a primary account number or token, and generates a push transfer message to facilitate transactions without exposing the actual account information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users manually input primary account numbers for transactions, then transaction accuracy can be improved, but user convenience deteriorates and time consumption increases
Solution Approach 1:
The patent introduces an alias as an intermediary that replaces the primary account number in user interactions. The alias serves as a mediator between the user and the actual account, allowing users to share and receive transactions without exposing or manually handling sensitive account numbers. This resolves the contradiction by maintaining accuracy through the intermediary while significantly improving convenience.
Solution Approach 2:
The patent creates a copy (alias) of the primary account number that can be freely shared and used for transactions. Instead of using the actual account number, the system uses this copied identifier that points to the real account through the intermediary service. This eliminates the need for manual input of the actual account number while ensuring accurate transaction routing.
2Adaptability or versatility
If users share primary account numbers for transactions, then transaction functionality is enabled, but privacy security deteriorates
Solution Approach 1:
The alias acts as a privacy-protecting intermediary that enables transaction functionality without exposing the primary account number. Users share the alias instead of the actual account number, and the intermediary service handles the mapping and transaction routing. This maintains full transaction functionality while preventing unauthorized access or misuse of the actual account information.
3Ease of operation
If users share email addresses or phone numbers for transactions, then ease of operation improves, but privacy security deteriorates
Solution Approach 1:
The patent introduces a dedicated alias system as an intermediary that serves the same ease-of-operation function as email addresses or phone numbers but with enhanced privacy protection. Instead of sharing personal contact information, users share these transaction-specific aliases that cannot be used for other purposes or identify the user in other contexts, thus improving privacy security while maintaining ease of operation.
4Object-affected harmful factors
If digital tags are introduced to replace primary account numbers, then privacy security improves, but device complexity increases
Solution Approach 1:
The digital tag (alias) system introduces complexity only at the intermediary service level, not at the user device level. Users simply use the alias without needing to understand or manage the underlying complexity of the mapping system. The intermediary service handles all the complex operations of storing, retrieving, and mapping aliases to account numbers, thereby improving privacy security while keeping the user experience simple.

AI summary
A method is disclosed. The method comprising receiving, by a transfer application on a first user's device, a payload comprising a digital tag associated with a second user, a transaction identifier, and a transaction amount. Transmitting, by the transfer application to a digital tag computer, the digital tag associated with the second user. Receiving, by the transfer application from the digital tag computer, a primary account number or token associated with the digital tag and transmitting, by the transfer application to an acquiring computer, a push transfer message.
