Dynamic codes store a redirect URL that you can change at any time from your dashboard. The image in your PowerPoint stays the same \u2013 only the destination changes. Static codes, including those generated by most add-ins, cannot be updated after creation.","inLanguage":"vi"},"inLanguage":"vi"},{"@type":"Question","@id":"https:\/\/pageloot.com\/nb\/how-to\/add-a-qr-code-to-a-powerpoint\/#faq-question-b7a5b673be4e","position":2,"url":"https:\/\/pageloot.com\/nb\/how-to\/add-a-qr-code-to-a-powerpoint\/#faq-question-b7a5b673be4e","name":"T\u00f4i n\u00ean t\u1ea3i m\u00e3 QR xu\u1ed1ng \u0111\u1ecbnh d\u1ea1ng t\u1ec7p n\u00e0o \u0111\u1ec3 d\u00f9ng trong PowerPoint?","answerCount":1,"acceptedAnswer":{"@type":"Answer","text":"PNG works well for most presentations.

For a room where the furthest viewer is around 15 feet away, you want the code to appear large and unobstructed on the projected display. Test the actual slide on a projected surface if possible, and always scan the code yourself before presenting to confirm it resolves correctly.","inLanguage":"vi"},"inLanguage":"vi"}]}},"_links":{"self":[{"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/posts\/55479","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/users\/17"}],"replies":[{"embeddable":true,"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/comments?post=55479"}],"version-history":[{"count":1,"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/posts\/55479\/revisions"}],"predecessor-version":[{"id":55524,"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/posts\/55479\/revisions\/55524"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/media\/55355"}],"wp:attachment":[{"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/media?parent=55479"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/categories?post=55479"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/tags?post=55479"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
