Age Verification via Video Projection in Self-Register Checkout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In self-register product sales systems, face image confirmation for age verification is unreliable due to small display screens on terminal apparatuses and requires customer cooperation, leading to potential inaccuracies in age confirmation.
Innovation Solution
A purchase management system that includes a server apparatus and a checkout machine, where the server receives item identification information from a mobile terminal, creates a list of items, and generates checkout information, and the checkout machine displays an age confirmation screen and acquires age confirmation information to ensure accurate age verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a still face image is transmitted to a terminal apparatus for age verification, then the verification process can be completed, but the small display screen makes it difficult for the clerk to correctly confirm the customer's age
Solution Approach 1:
The patent transitions from displaying a still face image on a small terminal screen to projecting a live video image on a large display screen at the checkout machine. This dimensional change from 2D small-screen display to large-screen projection enables the clerk to clearly see the customer's face and accurately determine age, resolving the contradiction between verification efficiency and accuracy.
2Ease of operation
If a camera in the self-register captures the customer's face image, then the verification process can proceed, but the customer must face the camera and cooperate, making the process cumbersome
Solution Approach 1:
The system automatically captures the customer's face image using the camera and processes it through video projection without requiring the customer to manually position themselves or cooperate with the camera. The automated capture and projection process eliminates the need for customer interaction, making the verification convenient while reducing process complexity.
3Reliability
If the face image is displayed on the terminal apparatus screen, then the age verification can be performed, but the small screen size prevents correct age confirmation
Solution Approach 1:
The patent introduces a video projection system as an intermediary between the face image capture and the clerk's visual inspection. Instead of directly displaying the image on the limited terminal screen, the system projects a magnified video image onto a large display screen, enabling reliable age verification while overcoming the constraint of small screen area.

AI summary
A server apparatus creates a list of items to be purchased by receiving item identification information scanned from a code attached to each item, generates checkout information based on the list of items to be purchased, and transmits the list to a mobile terminal. A checkout machine acquires the checkout information from the mobile terminal, and displays an age confirmation screen when an item requiring an age confirmation is included in the list of items to be purchased. The checkout machine completes the age confirmation when acquiring age confirmation information.
