Point-of-sale scanner with ultraviolet filter for currency authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing UV scanners for verifying identification cards and currency authenticity are often hardware- and software-incompatible with conventional point-of-sale systems, making them inconvenient and costly for infrequent use, and require additional training and storage for POS operators.
Innovation Solution
A point-of-sale scanner system that captures infrared images of barcodes and illuminates currency with UV light, using a filter to selectively allow or block UV light, allowing for authentication of bills and identification cards within the same device, with audio and haptic feedback for verification, and communication with a POS computer or remote server for determining authenticity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate UV scanner is integrated into the POS system, then currency and ID verification capability is improved, but device complexity and cost increase
Solution Approach 1:
The patent combines the UV verification function with the existing POS scanner into a single integrated device. The UV light source, filter, and image sensor are merged with the scanner's existing components, allowing both barcode scanning and UV verification to be performed by one device rather than requiring separate scanners.
Solution Approach 2:
The integrated scanner is designed to perform multiple functions: standard barcode/QR code scanning for point-of-sale operations, UV illumination for currency authentication, and ID card verification. This multi-functional design eliminates the need for separate dedicated UV scanning devices while maintaining all necessary capabilities.
2Adaptability or versatility
If a UV scanner is added to the POS system, then authentication capability is improved, but ease of operation deteriorates due to additional training requirements
Solution Approach 1:
The UV verification function is merged into the existing scanner workflow. Operators use the same device and similar operational procedures for both barcode scanning and UV verification, eliminating the need to learn and manage a separate device. The integrated design maintains consistent user interface and operation patterns.
3Adaptability or versatility
If a UV scanner is integrated into the POS system, then verification capability is improved, but loss of time increases due to additional management and storage requirements
Solution Approach 1:
The UV verification components are integrated within the existing scanner housing and operational framework. The device requires no separate storage when not in use, as it remains part of the POS system. Management tasks such as filtering, calibration, and maintenance are handled through the existing system infrastructure rather than requiring separate procedures.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides a cost-effective and compatible solution for verifying currency and identification card authenticity within existing POS systems, reducing the need for additional training and storage, and enhancing operational efficiency by integrating UV scanning capabilities into standard POS operations.
Implementation Method 1
configuring an ultraviolet filter mounted within a point-of-scale scanner to allow the passage of ultraviolet light within; The ultraviolet filter may be re-configured to block the passage of ultraviolet light
Implementation Method 2
illuminating the bill of currency with ultraviolet light emitted from the point-of-sale scanner
Implementation Method 3
capturing, with the point-of-sale scanner while the passage of ultraviolet light is allowed, an image of the bill of currency that includes a presence or absence of a fluorescent response to the ultraviolet light
Data Source
AI summary
Verifying the authenticity of a bill of currency includes configuring an ultraviolet filter mounted within a point-of-sale scanner to allow the passage of ultraviolet light within, illuminating the bill of currency with ultraviolet light, capturing, with the point-of-sale scanner, an image of the bill of currency, and determining if the bill of currency is authentic by analyzing the image.
