For a display scanned from 1 meter, the code should be at least 10 cm wide. For general digital signage, a minimum of 2 \u00d7 2 inches is a reasonable starting point, with size increasing as viewing distance grows. Always test at the actual display size and distance before going live.","inLanguage":"cs"},"inLanguage":"cs"},{"@type":"Question","@id":"https:\/\/pageloot.com\/qr-codes-on\/displays-and-screens\/#faq-question-a51bbbdaf65a","position":2,"url":"https:\/\/pageloot.com\/qr-codes-on\/displays-and-screens\/#faq-question-a51bbbdaf65a","name":"Mohu zm\u011bnit, na co odkazuje QR k\u00f3d na obrazovce, ani\u017e bych aktualizoval design?","answerCount":1,"acceptedAnswer":{"@type":"Answer","text":"Yes, if you use a dynamic QR code. Dynamic codes use a redirect URL, so you can update the destination in your account dashboard at any time \u2013 the code itself stays the same. This is especially useful for digital signage that promotes rotating campaigns or time-sensitive offers, since you avoid redesigning or redeploying the display every time the linked content changes.","inLanguage":"cs"},"inLanguage":"cs"},{"@type":"Question","@id":"https:\/\/pageloot.com\/qr-codes-on\/displays-and-screens\/#faq-question-7fd7fb7d4f15","position":3,"url":"https:\/\/pageloot.com\/qr-codes-on\/displays-and-screens\/#faq-question-7fd7fb7d4f15","name":"Pro\u010d se m\u016fj QR k\u00f3d na obrazovce neskenuje spolehliv\u011b?","answerCount":1,"acceptedAnswer":{"@type":"Answer","text":"The most common causes are insufficient contrast between the code and its background, a quiet zone that has been cropped or crowded by surrounding design elements, and a code that is too small for the viewing distance. On screens, display brightness and glare can also interfere. Check that your code uses a dark pattern on a light background, maintains a clear four-module quiet zone on all sides, and meets the size requirements for your expected scanning distance. Test on multiple devices to confirm compatibility.","inLanguage":"cs"},"inLanguage":"cs"}]}},"_links":{"self":[{"href":"https:\/\/pageloot.com\/cs\/wp-json\/wp\/v2\/posts\/2418","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pageloot.com\/cs\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/pageloot.com\/cs\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/pageloot.com\/cs\/wp-json\/wp\/v2\/users\/17"}],"replies":[{"embeddable":true,"href":"https:\/\/pageloot.com\/cs\/wp-json\/wp\/v2\/comments?post=2418"}],"version-history":[{"count":4,"href":"https:\/\/pageloot.com\/cs\/wp-json\/wp\/v2\/posts\/2418\/revisions"}],"predecessor-version":[{"id":54969,"href":"https:\/\/pageloot.com\/cs\/wp-json\/wp\/v2\/posts\/2418\/revisions\/54969"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pageloot.com\/cs\/wp-json\/wp\/v2\/media\/54415"}],"wp:attachment":[{"href":"https:\/\/pageloot.com\/cs\/wp-json\/wp\/v2\/media?parent=2418"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/pageloot.com\/cs\/wp-json\/wp\/v2\/categories?post=2418"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/pageloot.com\/cs\/wp-json\/wp\/v2\/tags?post=2418"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
