The one or more processors may be configured to monitor an output of the at least one photosensitive sensor, determine that the output is indicative of an obstruction on the display screen based on the output indicating a change to the luminance of the viewing surface of the display screen, and disable one or more operations of the transaction device based on determining that the output is indicative of the obstruction on the display screen."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Obstruction detection of a transaction device display screen","description":"In some implementations, a transaction device may include a display screen, at least one photosensitive sensor configured to detect a luminance of a viewing surface of the display screen, and one or m","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11488454","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
