The layered two-dimensional code is formed as a surface layer by layering a plurality of code layers (for example, code layers 1, 2, and 3) each having information cells (1a′, 1a″, and the like) arranged in a two-dimensional matrix and by integrating the plurality of code layers. An index information code 1c essentially including the information of an RGB value of each code layer is included at one part of the surface layer. When the information cells (1a′ and 1a″) of the code layers 1 and 2 are superposed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Layered two-dimensional code, creation method thereof, and read method","description":"The present invention provides a layered two-dimensional code which can be considerably improved in the data capacity thereof without increasing the area thereof by integrating a plurality of two-dime","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8511562","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.
