NFC Antenna Configuration for Mobile Payment Terminal Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional mobile devices are not suited to operate effectively as payment terminals due to their design and technology, particularly with near-field communication (NFC) systems, which are limited by lower data transmission rates and proximity requirements.
Innovation Solution
A payment terminal optimization application is executed on the user device to determine and optimize the placement of a payment enabled card, using a guide scan indicator to guide the card along the device's back side, allowing the device's antenna configuration to scan and determine the optimal payment location on the device's display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mobile devices utilize NFC systems for payment terminal operation, then payment functionality is enabled, but data transmission rate is limited and transmission distance is restricted to a few centimeters
Solution Approach 1:
The mobile device is configured to perform multiple functions: it operates as both a traditional mobile communication device and as a payment terminal. The NFC antenna configuration enables the device to universally communicate with both mobile networks and payment systems, allowing a single device to serve dual purposes without requiring separate dedicated hardware for each function.
Solution Approach 2:
The patent utilizes the existing NFC antenna configuration parameters and repurposes them for payment terminal operations. By changing the operational mode and software configuration rather than physical hardware parameters, the device achieves payment functionality while maintaining the inherent NFC transmission characteristics. The optimization focuses on software-level parameter adjustments to maximize the utility of the existing NFC infrastructure.
2Use of energy by moving object
If NFC systems operate at lower transmission data rates, then power consumption is reduced, but payment processing time increases
Solution Approach 1:
The system performs preliminary actions by pre-configuring the NFC antenna for optimal payment terminal operation and pre-establishing communication protocols. The mobile device is prepared in advance with the necessary payment terminal software and settings, so that when a payment transaction is initiated, the system can immediately engage in efficient data exchange without requiring time-consuming setup or configuration during the actual payment process.
3Ease of operation
If mobile devices are designed primarily as communication devices, then communication functionality is optimized, but payment terminal performance is insufficient
Solution Approach 1:
The mobile device employs dynamic functionality where the same hardware infrastructure (NFC antenna) is adaptively switched between communication mode and payment terminal mode based on operational requirements. The system dynamically adjusts its operational state, allowing the device to transition seamlessly between being a communication device and a payment terminal, with the NFC configuration serving both purposes effectively depending on the active application or mode.

AI summary
A system includes a processor and a non-transitory computer readable medium coupled to the processor. The non-transitory computer readable medium includes code, that when executed by the processor, causes the processor to receive input from a user of a user device to generate an optimal payment location on an application display, generate a first boundary of the optimal payment location on the application display of the user device based upon a first motion of a payment enabled card in a first direction and generate a second boundary of the optimal payment location on the application display of the user device based upon a second motion of the payment enabled card in a second direction. The first boundary and the second boundary combine to form defining edges of the optimal payment location.
