Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual testing of electronic card readers in POS systems is a time-consuming and repetitive process, requiring multiple cards from different vendors to ensure both magnetic strip and chip reading functions are working properly.
Innovation Solution
An automated electronic card reader testing system comprising a robot assembly with servomotors and a control system that can selectively swipe or insert cards into POS system slots, utilizing a disc with mounts to secure and advance cards for testing, and optionally integrating with a computer program to automate the testing protocol.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual testing is used to verify card reader functionality, then testing can be performed with flexibility, but the process is time-consuming and repetitive
Solution Approach 1:
The system enables automated self-testing of card readers through a robot assembly that automatically performs swiping and dipping operations without human intervention. The control system manages the entire testing process autonomously, selecting cards and executing test sequences to verify magnetic strip and chip functionality.
Solution Approach 2:
The patent replaces manual mechanical operations with an automated robot assembly driven by servomotors. The robot mechanically manipulates cards through programmed motions, substituting human hands and replacing repetitive manual testing actions with controlled mechanical automation.
2Reliability
If multiple cards from different vendors are tested manually, then comprehensive functionality verification is achieved, but the complexity of the testing process increases
Solution Approach 1:
The robot assembly is designed with universal card handling capabilities that can accommodate multiple card types from different vendors. The system uses a standardized card holder and slot interface that works with various card formats, enabling one testing device to verify functionality across diverse card types without requiring separate testing equipment for each card vendor.
Solution Approach 2:
The testing system segments the card reader functionality into distinct testable components: magnetic strip reading and chip reading. By separating these functions and testing them independently through different card insertion methods (swiping for magnetic strip, dipping for chip), the system comprehensively verifies reliability while managing complexity through structured test sequences.
3Productivity
If automated robot assembly is used for card testing, then testing speed and consistency are improved, but the device complexity increases
Solution Approach 1:
The robot assembly incorporates dynamic components including a rotatable disc with card holders and articulated arms with hinges that can adjust positions. The servomotors provide dynamic control of card presentation angles and insertion forces, allowing the system to adapt to different card types and test scenarios while maintaining automated high-speed operation.
Solution Approach 2:
The patent introduces intermediary components between the robot and card reader, including a card holder that interfaces with both the robot's gripping mechanism and the card reader slot. This intermediary simplifies the robot's task by providing a standardized interface, reducing overall system complexity while enabling automated operation.

AI summary
An electronic card reader testing system includes a robot assembly that is used to manipulate one or more credit cards, debit cards, gift cards, or similar electronic cards, and selectively swipe one of the electronic cards through a first slot of the electronic card reader and/or selectively insert (or “dip”) one of the electronic cards into the second slot of the electronic card reader. Operation of the robot assembly is managed by a control system. The testing system may also include a computer program that operably connects the control system of the robot assembly to a point-of-sale (POS) system, thus further automating the testing protocol.
