POS Currency Recognition via Image Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing currency conversion methods at Point-Of-Sale (POS) terminals are time-consuming and error-prone, relying on outdated tables or human input, which hampers customer service and business efficiency.
Innovation Solution
Implementing a system that uses imaging devices, such as cameras or bill validators, to automatically identify currency denomination and value, converting it to a standard denomination for seamless transaction processing on POS terminals, either locally or via network-accessed currency conversion data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual currency input and conversion methods are used at POS terminals, then currency transactions can be processed, but the process is time-consuming and error-prone
Solution Approach 1:
The patent replaces manual mechanical input methods with an automated image recognition system. A camera captures images of currency, and software automatically identifies denomination and calculates conversion, eliminating manual data entry and reducing both time consumption and human error
Solution Approach 2:
The system enables self-service currency processing where the POS terminal automatically detects currency denomination through image capture and performs conversion calculations without requiring manual intervention from cashiers or customers, thereby improving both speed and accuracy
2Reliability
If outdated currency conversion tables are used, then conversion can be performed, but the data is not current and errors occur
Solution Approach 1:
The system performs preliminary actions by capturing currency images and identifying denomination before the actual transaction conversion is needed. This pre-identification ensures accurate, up-to-date conversion data is ready when required, eliminating delays associated with manual table updates
Solution Approach 2:
The system incorporates feedback mechanisms where conversion rates and data can be continuously updated based on current market conditions. The automated system receives and processes updated conversion data, ensuring the most current rates are always used for transactions without manual intervention
3Productivity
If automated image recognition is implemented, then processing speed and accuracy improve, but system complexity increases
Solution Approach 1:
The patent integrates multiple functions into a single unified system. The POS terminal combines traditional transaction processing with image capture, currency identification, and automatic conversion calculation, allowing one device to perform multiple functions without proportionally increasing complexity
Solution Approach 2:
The system uses an intermediary software layer that bridges the camera hardware and the POS terminal's transaction processing system. This intermediary handles image processing and currency identification, translating visual data into format compatible with existing POS systems without requiring complete system redesign

AI summary
Various embodiments herein each include at least one of systems, methods, software, and data flows for automatic processing of foreign currency tenderings, such as on Point-Of-Sale (POS) terminals and other devices and system on which currency transactions may be conducted. One method embodiment includes receiving an image of an image flow captured by a camera of a scanner and determining whether a currency item is present in the image. In such embodiments, when a currency item is determined to be present in the image, sending a data representation of a received currency denomination and value as a currency tender input to a process of a POS terminal.
