Payment Terminal Connector Disconnection Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic payment terminals are vulnerable to fraud and hacking, with existing anti-theft methods being ineffective in preventing fraudulent activities, such as substitution or hacking, which can go undetected for extended periods.
Innovation Solution
Implementing a closed-loop control system that continuously monitors the connection between the central control unit and the main connector of the terminal, using a test signal to detect any disconnection, and switching to a blocked state if a break is detected, thereby preventing further fraudulent use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If daily weighing is used to detect terminal substitution, then fraudulent acts can be detected, but the technique does not prevent hacking and is not very dissuasive
Solution Approach 1:
The patent implements preliminary action by establishing a control loop connection before fraudulent acts can occur. The system proactively monitors the connection between the central control unit and main connector, detecting disconnections in real-time rather than through periodic weighing. This continuous monitoring prevents fraudulent manipulation by immediately detecting and responding to unauthorized actions, making the terminal more dissuasive against hackers.
2Reliability
If padlocks or hardware anti-theft devices are used, then terminal security is improved, but additional hardware is required which is not optimal
Solution Approach 1:
The patent replaces mechanical anti-theft devices like padlocks with an electronic control loop system. Instead of using physical hardware to prevent theft, the system uses electrical connection monitoring to detect unauthorized disconnections. This substitution eliminates the need for additional mechanical hardware while providing equivalent or superior security through intelligent detection and response mechanisms.
3Ease of operation
If the terminal remains operational after connector disconnection, then ease of operation is maintained, but fraudulent use can continue unchecked
Solution Approach 1:
The patent implements feedback by continuously monitoring the control loop connection and using this information to control terminal operation. When a disconnection is detected, the system receives feedback about the unauthorized action and responds by blocking further operations. This feedback mechanism ensures that fraudulent transactions cannot continue while maintaining normal operation during legitimate use, effectively balancing availability and security.

AI summary
A method for detecting a disconnection of a main connector of an electronic payment terminal is proposed, characterized in that it comprises the following steps: - detection (10) of a break in a connection control loop between a central control unit, housed in the terminal, and the main connector; - in the event of positive detection of a break, configuration (20) of the terminal in a blocked state.
