Landline Payment Tokenization With Merchant Identity Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to provide secure payment transactions over landlines due to the inability to verify merchant identity, require verbal disclosure of sensitive payment information, and lack tokenization and encryption capabilities.
Innovation Solution
A computing device that receives a merchant identifier over a landline, queries a database to verify the merchant, retrieves a token associated with the user's primary account number, and transmits the token securely to the merchant using encryption, enabling real-time verification and secure payment without exposing the account number.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an individual verbally reads the PAN to a representative through the landline to make a remote payment, then the payment can be processed, but the PAN may be stolen by a fraudster
Solution Approach 1:
The patent extracts the sensitive PAN from the communication process by introducing a token that represents the PAN. The token is generated by a tokenization service and transmitted instead of the actual PAN, thereby removing the security vulnerability while maintaining payment functionality
Solution Approach 2:
The patent introduces a tokenization service as an intermediary between the user and the payment processor. This service generates tokens that mediate the payment transaction, allowing the PAN to remain secure on the user's device while still enabling payment processing
2Productivity
If the individual provides the PAN to the merchant over the landline, then the transaction can be completed, but the PAN may be intercepted by a fraudster
Solution Approach 1:
The patent extracts the PAN from the transmission path by replacing it with a token. The token contains no sensitive information that can be exploited by interceptors, yet it enables the same payment processing functionality
Solution Approach 2:
The patent creates a functional copy of the PAN in the form of a token. This token copy can be transmitted and processed like the original PAN but cannot be used to compromise the actual account information
3Reliability
If current security measures such as tokenization and encryption are used, then the PAN can be protected during transmission, but these measures cannot be used when making a payment over a landline
Solution Approach 1:
The patent creates a universal payment system that works across multiple communication channels including landlines, mobile phones, and internet. The tokenization mechanism is channel-agnostic, allowing the same security approach to be applied regardless of the communication medium

AI summary
A computing device for securely transacting over a landline is provided. The computing device is configured to receive, through a landline, from a merchant in response to a transaction request by a user, a merchant identification message including a merchant identifier, extract the merchant identifier from the merchant identification message, query a database of merchant data including a plurality of merchants and a plurality of merchant identifiers, identify, in response to the query, the merchant by matching the extracted merchant identifier against the plurality of merchant identifiers in the database, retrieve, in response to successfully identifying the merchant, a token associated with a PAN of the user, generate a token message including the token, transmit the token message to the merchant through the landline, and receive, from a payment processor, a confirmation message indicating a payment using the PAN was made in response to the merchant receiving the token.
