POS Card Reader Computer Vision User Absence Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users often forget their account-linked cards in point of sale (POS) devices or card readers, leading to inconvenience and additional costs for both the user and the issuing institution.
Innovation Solution
Implementing a POS device equipped with a processor, card sensor, and camera that uses computer vision techniques to detect when a user has left the area without retrieving their card, and sends a notification to the user to remind them to retrieve the card.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a card reader is configured to ingest or swallow the account-linked card to prevent unauthorized access, then security is improved, but user convenience deteriorates as the user cannot retrieve the card and must go through replacement procedures
Solution Approach 1:
The system performs preliminary detection of user absence using computer vision before the card is ingested. By detecting that the user has left the area using camera-based monitoring, the system can alert the user or prevent card ingestion, thereby maintaining security while avoiding the inconvenience of card loss
Solution Approach 2:
The system implements feedback by continuously monitoring the area around the card reader using a camera and detecting user presence or absence. When the system detects that the user has left without retrieving the card, it provides feedback through alerts or notifications, allowing the user to return and retrieve the card before ingestion occurs
2Reliability
If the card reader ingests the card to prevent unauthorized access, then security is improved, but time loss increases as the user must cancel and replace the card
Solution Approach 1:
The system performs preliminary detection of user absence using computer vision technology before card ingestion occurs. By monitoring the area around the card reader and detecting when the user has left, the system can trigger alerts or notifications to remind the user to retrieve their card, thereby preventing the time-consuming card replacement process
Solution Approach 2:
The system implements real-time feedback by using camera-based monitoring to detect user presence or absence. When the system determines that the user has left without retrieving the card, it provides immediate feedback through alerts, giving the user an opportunity to return and retrieve the card before ingestion, thus avoiding time loss
3Reliability
If the card reader ingests the card to prevent unauthorized access, then security is improved, but cost increases due to replacement card creation and shipping
Solution Approach 1:
The system performs preliminary detection of user absence using computer vision before card ingestion. By detecting user absence through camera monitoring and providing alerts, the system prevents unnecessary card ingestion events, thereby avoiding the costs associated with creating and shipping replacement cards
Solution Approach 2:
The system implements feedback through camera-based user presence detection and alert mechanisms. When the system detects that a user has left without retrieving their card, it provides feedback to alert the user, enabling them to return and retrieve the card, thus preventing the institution from incurring replacement card costs

AI summary
A computer vision card reader and/or point of sale device is described. The device is configured to sense when a user inserts a card into a card reader and to determine when a user departs or is about to depart from the device without retrieving the card. The device may issue an audible or visible alert to the user, reminding the user to retrieve the card. The device may additionally send a notification to a mobile device associated with the user that reminds the user that he has left a card at the point of sale. In some embodiments, message sent to the user contains a code and, upon entry of the code, the point of sale or card reader device returns the card to the user.
