Digital Pass Verification via Scannable Codes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for effective systems to verify whether individuals have recently tested negative for infectious diseases before allowing them access to certain locations, as outbreaks of contagious diseases pose risks to public health and safety.
Innovation Solution
A digital pass verification system that uses electronic devices to generate and manage digital passes, which include machine-readable codes indicating negative test results, allowing verifiers to quickly confirm the health status of individuals attempting to access restricted areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual verification of health status is used, then system complexity is low, but verification time and efficiency are poor
Solution Approach 1:
The patent uses digital copies of health pass documents (electronic health passes, QR codes, barcodes) instead of physical paper documents. Verifiers can scan these digital codes using mobile devices to instantly verify health status, eliminating manual document checking while maintaining simplicity for users. This resolves the contradiction by providing fast automated verification through digital copying without requiring complex centralized systems.
Solution Approach 2:
The system allows individuals to self-generate and present their own health verification codes through mobile applications. Users automatically receive and display their digital health passes after testing, eliminating the need for centralized issuance and manual verification processes. This self-service approach dramatically improves verification efficiency while keeping the overall system architecture simple and distributed.
2Reliability
If centralized health pass management system is implemented, then verification reliability is improved, but system complexity and implementation difficulty increase
Solution Approach 1:
The patent segments the health verification system into independent components: testing facilities generate results, users store digital passes locally on their devices, and verifiers scan codes independently. Each component operates autonomously without requiring constant connection to a centralized server. This segmentation maintains verification reliability through distributed validation while avoiding the complexity of centralized management infrastructure.
Solution Approach 2:
The system stores and processes health verification data locally on individual user devices rather than requiring centralized storage. Each user's mobile device contains their personal health pass information and can present it independently. This local quality approach ensures verification reliability at the point of use while eliminating the need for complex centralized databases and network infrastructure.
3Object-affected harmful factors
If digital health passes are required for access, then infection transmission risk is reduced, but ease of operation decreases due to technology requirements
Solution Approach 1:
The patent utilizes mobile devices that users already possess for multiple purposes (communication, navigation, etc.) to also serve as health verification tools. The same smartphone or tablet used for daily activities can store, display, and present health passes without requiring separate dedicated hardware. This universality reduces infection risk through digital verification while maintaining ease of operation by leveraging existing user technology.
Solution Approach 2:
The system creates simplified digital copies of health verification information in the form of scannable QR codes or barcodes that can be instantly displayed on mobile screens. These visual codes are easy to present and scan, requiring minimal user interaction beyond opening an app. This copying approach effectively reduces transmission risk through contactless verification while preserving ease of operation through simple, intuitive interfaces.

AI summary
Digital pass verification systems and methods are disclosed herein. One or more servers are to distribute instructions on a network. The instructions, when executed, cause a first device carried by a person to at least: access a result of a diagnostic test performed on the person, the result provided by a second device; generate a machine-readable code in response to the result being negative; and display the machine-readable code on a display of the first device to enable the person to gain access to a location.
