Turnstile Piggybacking Detection for Single-User Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security systems with card reader access full height turnstiles are vulnerable to unauthorized entry through piggybacking, where multiple individuals attempt to pass through the turnstile using a single authorized credential.
Innovation Solution
A separation system incorporating a piggybacking detection device that uses sensors and AI algorithms to detect the presence of multiple users within a count area, communicating with a turnstile controller to control the rotation of rotary panels, ensuring only one authorized user can pass through at a time.

Engineering Contradiction Analysis
1Reliability
If a card reader access full height turnstile is used, then authorized access control is improved, but vulnerability to piggybacking increases
Solution Approach 1:
The piggybacking detection device performs preliminary detection of multiple users in the count area before the turnstile is unlocked. By detecting the presence of multiple users in advance and preventing unlock in such cases, the system proactively blocks piggybacking attempts before they can compromise security.
Solution Approach 2:
The system continuously monitors the count area for user presence and provides real-time feedback to the turnstile controller. When multiple users are detected, the system feedback mechanism prevents the turnstile from unlocking, thereby dynamically adjusting access control based on current conditions to prevent piggybacking.
2Ease of operation
If multiple users are allowed in the count area, then ease of operation is improved, but security control deteriorates
Solution Approach 1:
The system performs preliminary detection of user presence in the count area before allowing turnstile operation. By checking for multiple users in advance, the system can prevent unlock commands from being executed, thereby maintaining single-passage control while still allowing efficient user flow when only one user is present.
Solution Approach 2:
The piggybacking detection device acts as an intermediary between users and the turnstile controller. It monitors user presence and mediates the unlock command by blocking it when multiple users are detected, thus enforcing single-passage control without directly interfering with legitimate single-user access.

AI summary
Separation systems, anti-piggybacking devices, computer program products and related methods for controlling access to a restricted area are provided. For example, a method for allowing single authorized entrance through a passage to control entrance into a restricted area of a facility can include, upon receiving an access granted signal, unlocking a lockable turnstile for an entry time period to permit the user to rotate a rotary panel assembly of the turnstile to enter the restricted area. The method can also include sensing, using a piggybacking detection device, a number of users in a count area within the turnstile while the turnstile is unlocked. Further, the method can include resetting the piggybacking detection device and locking the turnstile after only the single user is detected in the counter area and the rotary panel assembly of the turnstile is rotated to a position in the turnstile in which the single user is allowed to enter the restricted area.
