Cardless Payment Authorization via Mobile Location and Biometrics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional point-of-sale credit card transactions require physical card swiping and often necessitate electronic signatures or PINs, which can be inconvenient and vulnerable to unauthorized transactions.
Innovation Solution
A method for processing cardless payment transactions where a customer provides consent and location-based authorization using their mobile device, allowing transactions to be processed without physical card presentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical card swiping is required for transactions, then transaction security is improved, but customer convenience and transaction speed deteriorate
Solution Approach 1:
The patent extracts the payment authentication function from the physical card itself and relocates it to a mobile device application. The mobile device stores payment credentials and uses location-based authentication (determining the device is within a predetermined distance of the merchant) combined with biometric or passcode verification to authorize transactions, eliminating the need for physical card swiping while maintaining security through multiple authentication factors.
Solution Approach 2:
The patent replaces the mechanical card-swiping system with an electronic/mobile-based system. Instead of physically inserting and swiping a card through a magnetic stripe reader, the system uses a mobile device with GPS/location services to determine proximity to the merchant and electronic authentication methods (biometrics, passcodes) to authorize the transaction, substituting mechanical interaction with electronic verification.
2Ease of operation
If physical card swiping is eliminated for cardless payments, then customer convenience is improved, but risk of unauthorized transactions increases
Solution Approach 1:
The patent implements preliminary authorization where the customer pre-approves the merchant to perform cardless payment transactions. The system determines the mobile device is within a predetermined distance of the merchant before allowing transactions, and requires customer authorization (biometric or passcode) at the time of purchase. This preliminary setup combined with real-time verification prevents unauthorized transactions while maintaining convenience.
Solution Approach 2:
The patent introduces multiple intermediary verification layers between the customer and the transaction: location-based verification (confirming the device is at the merchant's location), pre-authorization setup (customer approving the merchant in advance), and real-time authentication (biometric or passcode verification at purchase). These intermediaries create security checkpoints that prevent unauthorized transactions without requiring physical card handling.
3Reliability
If electronic signatures or PINs are required during transactions, then transaction authorization is improved, but transaction time and complexity increase
Solution Approach 1:
The patent implements self-service authentication where the customer's mobile device automatically performs biometric verification (fingerprint, facial recognition) or passcode entry without requiring interaction with the merchant's point-of-sale system. The authentication is handled entirely by the customer's own device in a seamless manner, eliminating the need for separate signature capture steps or complex PIN entry at the merchant terminal, thus reducing transaction time while maintaining authorization security.

AI summary
Systems and methods for card interfacing are disclosed. In some examples, a system displays, in a user interface (e.g., of a wallet application), a plurality of representations of transaction mediums (e.g., cards). The system receives, through the user interface, a user input corresponding to a selection of a first representation of a first transaction medium from the plurality of representations of transaction mediums. The system retrieves account information associated with the first transaction medium, and facilitates a transaction using the account information associated with the first transaction medium.
