Access Control Group Management via Card Reader
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access control systems lack a straightforward method for an administrator to temporarily restrict access to all users across multiple doors associated with card readers during high-security situations without manual intervention in the access controller or host system.
Innovation Solution
The system allows administrators to define groups of card readers and use management cards (e.g., forbid and cancel forbid cards) to update the database, enabling immediate restriction or reinstatement of access across multiple doors, allowing access to be denied or granted via a single card reader action.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an administrator manually intervenes in the access controller or host system to restrict access during high-security situations, then access control reliability is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The system enables administrators to self-service access restriction operations by swiping management cards at card readers. The card reader and access controller automatically process the restriction command and update the database without requiring manual intervention in the host system, making the operation as simple as presenting a card while maintaining reliable access control
Solution Approach 2:
Management cards serve as intermediaries between administrators and the access control system. The cards carry encoded instructions that automatically communicate restriction commands to the access controller when presented at card readers, eliminating the need for direct manual configuration of the host system
2Reliability
If an administrator manually configures access restrictions in the access controller or host system, then access control reliability is improved, but loss of time increases
Solution Approach 1:
Management cards are pre-configured with encoded instructions for access restriction before being issued to administrators. When an administrator needs to restrict access during a high-security situation, they simply present the pre-prepared management card at any card reader, and the system immediately executes the restriction and updates the database, eliminating time-consuming manual configuration
Solution Approach 2:
The system automatically processes management card presentations by extracting the card number, identifying the associated door group, and updating the database to deny access for all cards in that group. This self-service automation eliminates the time loss associated with manual administrator intervention in the host system
3Measurement precision
If the system requires direct access to the access controller or host system for access restriction, then control precision is improved, but ease of operation deteriorates
Solution Approach 1:
Management cards act as intermediaries that carry precise control instructions to the access control system. When presented at a card reader, the card's encoded information automatically triggers the access controller to deny access for specific door groups, maintaining precise control while eliminating the need for administrators to directly access or configure the host system
4Measurement precision
If the system updates the database for each individual card restriction request, then measurement precision is improved, but productivity deteriorates
Solution Approach 1:
The system merges multiple individual access restriction operations into a single group-based update. When a management card is presented, the system identifies the associated door group and updates the database to deny access for all cards in that group simultaneously, maintaining precise tracking of which cards are restricted while dramatically improving productivity by avoiding individual updates for each card

AI summary
Systems and methods of preventing access to users of an access control system, for example, by facilitating an administrator temporarily forbidding access by all users to one or more areas secured by one or more doors associated with one or more card readers. Some methods can include reading a first management card at a first card reader, identifying a first group of which the first card reader is a part, identifying a plurality of card readers in the first group, and updating a database device to indicate that access via the first card reader or any card reader in the plurality of card readers is forbidden.
