RFID Notification for Commodity Detection in Sales Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Customers often forget to remove commodities from the placement portion after settlement processing in commodity sales processing apparatuses, leading to incomplete transactions and potential losses.
Innovation Solution
A commodity sales processing apparatus equipped with a placement portion, an antenna for RFID tag signal reception, a reading component for RFID tag information, and a notification component, such as a light emitting unit or speaker, to alert the customer after settlement processing that the commodity is still in the placement portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If settlement processing is performed without notification, then processing speed is improved, but reliability of complete transaction is worsened
Solution Approach 1:
The notification component issues a notification before the settlement processing is fully completed, alerting the customer to remove the commodity. This preliminary action ensures that the customer is aware of the pending transaction and can take appropriate action, thereby preventing incomplete transactions while maintaining efficient processing.
Solution Approach 2:
The system provides feedback to the customer through the notification component, informing them that settlement processing is underway and that they should remove the commodity. This feedback loop ensures that the customer is aware of the system's state and can respond appropriately, improving transaction completeness without sacrificing processing speed.
2Reliability
If notification component is added, then reliability of complete transaction is improved, but device complexity is worsened
Solution Approach 1:
The notification component serves multiple functions: it alerts the customer to remove the commodity, indicates that settlement processing is underway, and can potentially provide other status information. By making this single component multi-functional, the system achieves improved reliability without proportionally increasing complexity.
Solution Approach 2:
The notification component automatically issues notifications based on the system's internal state without requiring additional manual intervention or complex control mechanisms. The system self-manages the notification process, improving reliability while minimizing the increase in device complexity.

AI summary
According to one embodiment, a commodity sales processing apparatus includes a placement portion, an antenna, a reading unit, a notification unit, and a control unit. A commodity is placed in the placement portion. The antenna receives a signal from an RFID tag included in the commodity placed in the placement portion. The reading unit reads information of the RFID tag based on the signal received via the antenna. The notification unit notifies that the commodity is placed in the placement portion. The control unit controls the notification unit after settlement processing.
