Smartphone QR Entry Verification for Pathogen Status Screening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is currently no efficient system for businesses to verify customer infection status, leading to economic challenges and customer fear of close contact with unknown infection status during the COVID-19 pandemic, potentially causing businesses to shut down or operate at reduced capacity.
Innovation Solution
A personal pathogen verification system using a computing device and mobile app to schedule tests, display QR codes for verification, and enforce entry rules based on test results, ensuring only qualified individuals enter areas of congregation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If businesses restrict admission to people with verified negative test results or antibody evidence, then customer safety and confidence improve, but system complexity and operational burden increase
Solution Approach 1:
The patent introduces a centralized verification server as an intermediary between testing facilities and businesses. This server manages test result databases, generates unique identifiers, and handles verification requests, thereby distributing system complexity away from individual businesses and enabling them to implement simple QR code scanning without building complex verification infrastructure
Solution Approach 2:
The patent uses QR codes as digital copies of verification data. Instead of requiring businesses to store and verify full test result records, the system generates QR codes containing encrypted verification tokens that can be scanned and validated remotely, significantly reducing the operational burden on businesses while maintaining verification reliability
2Object-affected harmful factors
If businesses implement pathogen verification systems, then transmission risk reduction improves, but time required for verification and entry processing increases
Solution Approach 1:
The system performs verification actions in advance by generating QR codes at the time of testing and storing results in the centralized database before the customer arrives at the business. This preliminary preparation eliminates the need for time-consuming on-site verification procedures, allowing quick QR code scanning and instant validation at the point of entry
Solution Approach 2:
The patent replaces manual verification processes with automated digital systems. QR code scanning and cryptographic validation occur automatically through mobile devices and servers, eliminating the need for manual review of test documents by staff, thereby dramatically reducing verification time while maintaining rigorous safety checks
3Productivity
If businesses operate without verification systems, then operational efficiency is maintained, but customer fear and economic shutdown risks increase
Solution Approach 1:
The system enables customers to self-verify their status by presenting QR codes from their own devices. Businesses simply scan codes rather than manually checking documents, and customers retain control of their verification data. This self-service approach maintains operational efficiency while building customer confidence through transparent, automated verification
Solution Approach 2:
The centralized verification server provides immediate feedback when QR codes are scanned, instantly confirming or rejecting verification status. This real-time feedback mechanism allows businesses to make rapid entry decisions without delays, maintaining operational efficiency while providing customers with immediate confirmation that their verification was successful, thereby reducing anxiety and fear
Data Source
AI summary
A smartphone and app executed on the smartphone are used for personal pathogen status verifying that allows an entity to control access to an area of congregation (AOC) at one or more points of entry (POE). In one embodiment, the system may be used for the SARS-CoV-2 virus, but may be similarly used for other pathogens.
