POS Integrating Device OCR Capture for Transaction Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional point-of-sale systems often experience errors when transferring the total amount from a register to a payment terminal, leading to inefficiencies, increased liability, and difficulties in reconciliation, particularly when handling credit card transactions.
Innovation Solution
An integrating device with a processor and video capture card captures images from the register, performs optical character recognition to identify the total amount, and outputs it directly to the payment terminal, eliminating the need for manual input and reducing physical handling of credit cards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual transfer of total amount from register to payment terminal is used, then device complexity is reduced, but manufacturing precision and reliability deteriorate due to frequent errors
Solution Approach 1:
The system uses optical character recognition (OCR) technology to capture an image of the total amount displayed on the register screen and automatically transfers it to the payment terminal. This copying approach eliminates manual data entry while maintaining system simplicity, resolving the contradiction between device complexity and transaction accuracy.
2Ease of operation
If manual input of total amount is used, then ease of operation is reduced due to errors requiring reversal, but device complexity is minimized
Solution Approach 1:
The system performs automatic capture and transfer of the total amount without requiring clerk intervention. The OCR technology independently identifies the total from the register display and inputs it to the payment terminal, eliminating manual operations and associated errors while improving checkout efficiency.
3Ease of operation
If physical handling of credit cards by clerk is required, then ease of operation is maintained, but object-generated harmful factors increase due to liability shift to business
Solution Approach 1:
The system extracts the total amount data directly from the register display through image capture and OCR, bypassing the need for physical credit card handling by the clerk. This eliminates the liability risk associated with physical card possession while maintaining smooth transaction flow.

AI summary
A method of linking a point-of-sale register and a payment terminal into an integrated point-of-sale system includes entering at least one item into the point-of-sale register, calculating a total cost of the at least one item, receiving an image from the point-of-sale register at an integrating device, the integrating device having a processor and a video capture card, locating the total cost in the image by identifying a target area, performing optical character recognition on the target area, and outputting a numerical total to a payment terminal.
