Access Control Device with Single Credential for Multiple Persons
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access control devices require each individual to possess their own proof of access authorization, which is inefficient and costly, especially in scenarios where multiple people need to access a restricted area.
Innovation Solution
An access control device that utilizes a control unit trained to receive and verify a single proof of access authorization, allowing a certain number of people (typically between 2 to 30) to access a restricted area without each needing their own proof.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each person needs their own access authorization credential, then security is maintained, but administrative complexity and cost increase
Solution Approach 1:
The patent combines multiple access authorizations into a single credential that can authorize multiple persons. The control unit is configured to recognize that one credential may represent multiple authorized individuals, thereby reducing the number of credentials to manage while maintaining security through the underlying identity verification of each person presenting the credential.
Solution Approach 2:
The access authorization credential is designed with multi-functionality to serve multiple purposes: it can authorize multiple different persons, work across different access points, and potentially serve different time periods. This universal credential reduces administrative overhead while maintaining security through contextual verification.
2Ease of operation
If multiple credentials are issued for multiple persons, then individual access control is precise, but data management expenditure increases
Solution Approach 1:
The system merges the management of multiple individual credentials into a single credential structure. Instead of creating, storing, and managing separate credential records for each person, the system uses one credential that can authorize multiple individuals, significantly reducing data storage and management requirements.
3Productivity
If a single credential authorizes multiple persons, then administrative efficiency improves, but verification complexity increases
Solution Approach 1:
The control unit implements feedback mechanisms to track and verify each person's authorization status. When a credential is presented, the system verifies the presenter's identity, checks against the authorized persons list, provides immediate verification feedback, and updates the authorization status accordingly. This automated feedback loop manages verification complexity while maintaining administrative efficiency.

AI summary
The invention relates to an access control device (1) for granting and blocking access by at least one person (10) to an access-restricted area, depending on the access authorization of the person (10), with at least one virtual lock (5) and/or with at least one physical lock (5) and a control unit (2), wherein the control unit (2) is configured and set up to receive an access authorization certificate (30) from a certificate issuer (3) for verifying the access authorization. The invention further relates to a method for access control of persons (10) to an access-restricted area.
