Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional payment verification methods using one-time passcodes are used, then security is maintained, but user convenience and transaction speed deteriorate
Solution Approach 1:
The patent extracts the verification process from the traditional one-time passcode system and replaces it with a tap-based authentication mechanism. The mobile device reads payment information directly from a physical financial instrument via NFC, eliminating the need for users to manually enter or verify passcodes, thereby improving convenience while maintaining security through the secure tap transaction.
Solution Approach 2:
The patent introduces an intermediary machine-readable code (QR code or similar) that bridges the provider and the mobile device. This code contains an embedded link to the provider website and initiates the payment process, serving as a mediator that streamlines the interaction between the user, mobile device, and payment system, reducing reliance on complex verification steps.
2Reliability
If complex verification processes are implemented to prevent fraud, then security is improved, but transaction time and system complexity increase
Solution Approach 1:
The patent performs preliminary actions by pre-configuring the mobile device with payment information from the physical financial instrument before the actual transaction. The device reads and stores the payment data in advance, so that during the transaction, only a simple tap and confirmation are needed, significantly reducing transaction time while maintaining security through pre-validated payment information.
Solution Approach 2:
The system enables self-service by allowing the mobile device to automatically read, process, and submit payment information without requiring manual verification steps. The device autonomously completes the payment process by tapping the physical instrument, retrieving information, and submitting it to the provider website, reducing both transaction time and system complexity.
3Productivity
If manual verification methods are used, then system complexity is reduced, but productivity and transaction speed decrease
Solution Approach 1:
The patent replaces manual verification mechanisms with automated electronic processes. Instead of manual passcode entry and verification, the system uses NFC technology to automatically read payment information from the physical financial instrument and electronically transmits it to the provider website, significantly increasing transaction speed while managing system complexity through standardized protocols.
Solution Approach 2:
The mobile application serves multiple functions: it acts as a scanner for machine-readable codes, an NFC reader for physical financial instruments, a web browser for accessing the provider website, and a payment processor. This multi-functionality consolidates what would otherwise require separate systems into a single device, improving productivity without proportionally increasing complexity.

Data Source
AI summary
Systems and methods for mobile device payment using tap are disclosed. In one embodiment, a method may include: reading, by a mobile application executed by a mobile electronic device, a machine-readable code comprising an embedded link to a provider website at a uniform resource locator (URL) provided by a provider of a good or service for a transaction involving the good or service; accessing, by the mobile application, the URL; receiving, by the mobile application and from the provider website, a payment by tap option; wirelessly receiving, by the mobile application, payment information from a physical financial instrument; providing, by the mobile application, the payment information to the provider website; and receiving, by the mobile application and from the provider website, confirmation of payment for the transaction.
