Displaced Scanner Status Indicator for POS Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current checkout systems face security issues due to obstruction of scanner status lights by checkout displays, which hinder the view of overhead security cameras, and integration of status lights into scanners interferes with barcode scanning, leading to scanning errors.
Innovation Solution
A system that includes a scanner with displaced scanner status indicators, such as multicolored LEDs on the horizontal top plate or a status pole, visible to overhead security cameras, which selectively activate or deactivate to indicate successful scans without interfering with the scanning process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If status lights are integrated into the scan plate of the scanner, then the status lights can be activated during scanning, but the illuminated status lights interfere with the barcode imaging process causing scanning errors
Solution Approach 1:
The patent divides the status light system into separate components: vertical status lights on the scanner tower and horizontal status lights on the scan plate, allowing independent control and positioning to avoid interference with the scanning process
Solution Approach 2:
The patent transitions from integrating status lights within the scan plate area to positioning them in different spatial dimensions (vertical tower and horizontal plate), creating separate light paths that do not interfere with barcode imaging
2Ease of operation
If the scanner is configured into the checkout terminals, then scanning functionality is provided, but the configuration obstructs the overhead camera's view of the scanner status lights
Solution Approach 1:
The patent segments the status light display into multiple locations (vertical tower and horizontal plate) that are distributed in space, ensuring that at least some status lights remain visible to overhead cameras while maintaining scanner functionality
Solution Approach 2:
The patent positions status lights in different spatial dimensions and orientations (vertical and horizontal) to create visibility paths for overhead cameras that do not require unobstructed views of the scanner configuration itself
3Adaptability or versatility
If checkout displays overhang and cover the area where status lights are activated, then display functionality is provided, but the status light visibility is blocked
Solution Approach 1:
The patent segments the status light activation area into zones above and below the display overhang, allowing status lights to be activated in multiple locations including areas not blocked by the display
Solution Approach 2:
The patent positions status lights in three-dimensional space at different heights and orientations relative to the display, creating visibility paths that bypass the display overhang obstruction
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
Enhances checkout security by allowing overhead cameras to detect item scanning without obstructing the view or interfering with barcode imaging, reducing theft and errors in both assisted and self-service checkouts.
Implementation Method 1
the scanner includes a light source and an image sensor
Implementation Method 2
At least one light within a field-of-view of an overhead security camera is selectively activated or deactivated as an indication for the determination
Data Source
AI summary
A scanner is integrated as a peripheral device into a POS terminal. Light Emitting Diodes (LEDs) are selectively activated and deactivated during item scanning for items being processed during a transaction at the POS terminal. The activation and deactivation of the LEDs are visible to an overhead security camera during the transaction. The selective activation and deactivation providing indications during the transaction as to whether the items are successfully scanned or unsuccessfully scanned during the transaction as the items are passed in front of at least one scan window of the scanner.
