NFC Reader Preferred Application List Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current NFC transactions require multiple taps for order, coupon, and payment processing, which is cumbersome and time-consuming, and merchants lack control over the priority of transaction applications used in these processes.
Innovation Solution
A system utilizing preferred application lists in an NFC reader, where a transaction terminal designates compatible application identifiers, and a mobile device with a PPSE application stores user-preferred identifiers, allowing the reader to determine and prioritize matched applications for a single tap transaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple NFC taps are used for order, coupon, and payment transactions, then transaction completeness is improved, but operation time and user convenience deteriorate
Solution Approach 1:
The patent combines multiple transaction types (order, coupon, payment) into a single NFC tap operation. The reader receives a list of application identifiers from the mobile device and processes all transaction types in one interaction, eliminating the need for separate taps for each transaction type while maintaining complete transaction processing.
Solution Approach 2:
The mobile device pre-configures a list of application identifiers with priority levels before the transaction. The reader uses this pre-sorted list to automatically select and process the appropriate application without requiring user intervention or multiple taps, thereby reducing operation time while ensuring complete transaction processing.
2Productivity
If the reader selects the highest priority application automatically, then operation speed is improved, but merchant control over transaction application selection deteriorates
Solution Approach 1:
The system dynamically adjusts application selection based on merchant-configured priority levels. The reader receives application identifiers sorted by priority from the mobile device and automatically selects according to the merchant's predetermined preferences, allowing both fast automatic operation and merchant control over which application is processed first.
Solution Approach 2:
The mobile device provides feedback in the form of a sorted application identifier list that reflects user-preferred priorities. The reader uses this feedback to automatically select the appropriate application, ensuring both rapid processing and adherence to merchant or user preferences without requiring manual selection.
3Ease of operation
If a single NFC tap is used for all transactions, then operation convenience is improved, but transaction processing capability deteriorates
Solution Approach 1:
The NFC reader is designed to handle multiple transaction types (order, coupon, payment) within a single tap operation. By receiving and processing a list of application identifiers that correspond to different transaction types, the reader maintains universal functionality and adaptability while providing the convenience of a single tap for all transactions.

AI summary
The subject matter described herein includes systems, methods, and computer readable media for utilizing one or more preferred application lists in a wireless device reader. A transaction terminal designates compatible application identifiers, where each of the compatible application identifiers is respectively associated with a transaction application that is compatible with the transaction terminal. A proximity payment system environment (PPSE) application is configured to store user preferred application identifiers, where each user preferred application identifier is respectively associated with a to transaction application stored on the mobile wireless device. A wireless device reader for receives the compatible application identifiers from the transaction terminal, and stores the compatible application identifiers in preferred applications lists (PALs).
