First type of data codes is mapped in the code area. The first type of data codes are coded as the codewords and indicating data to be disclosed. An end identification code is added to an end of a code string composed of the first type of data codes, the end identification code showing the end. Second type of data codes are mapped after the end identification code in the code area, the second type of data codes being coded as the codewords and indicating data to be kept in secret. Filler codes showing no data after the second type of data codes are mapped to fill up the code area, when a total amount of the codewords in the code area is less than a capacity of the code area."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for producing two-dimensional code and reader for reading the two-dimensional code","description":"A method of producing a two-dimensional code having a code area in which data codes coded as codewords are mapped.
