It was invented for the purpose of tracking vehicles during manufacturing; it was made to allow high speed component scanning.  QR codes contain data for an identifier, or tracker or locator that directs you to an application or a website. A QR code uses four standard encoding modes :<\/p>\n\n\n\n<ol><li>numeric  <\/li><li>alphanumeric <\/li><li>byte\/binary<\/li><li>kanji<\/li><\/ol>\n\n\n\n<p>Due to its fast readability and efficient storage capacity compared to UPC bar-codes the QR code system became popular outside the automotive industry and it&#8217;s applications include time tracking, identifying item, tracking products, managing documents and marketing. The way QR code look is that it consists of black squares arranged in a square grid on a white background, which can be read by an imaging device like a camera.<\/p>\n\n\n\n<p>QR codes usage in a broader context in present time includes both commercial tracking applications and convenience-oriented applications aimed at mobile users, those uses can be :<\/p>\n\n\n\n<ul><li>To display text to the user<\/li><li>Open a web page on the user&#8217;s device <\/li><li>To open a uniform resource identifier (URI)<\/li><li>Add a V card contact to the user&#8217;s device <\/li><li>Connect to a wireless network <\/li><li>To compose an email or a text message  <\/li><\/ul>\n\n\n\n<p>Their are also some features that distinguish the QR code such as:<\/p>\n\n\n\n<ul><li>High capacity encoding of data<\/li><li>Kanji and kana capability<\/li><li>Small printout size<\/li><li>Dirt and damage resistant<\/li><li>Readable from any direction<\/li><li>Structured and Appending feature<\/li><\/ul>\n\n\n\n<p>Finally, we mention the 5 types of QR code: <\/p>\n\n\n\n<ul><li>QR code model 1 and model 2 <\/li><li>Micro QR code<\/li><li>IQR code <\/li><li>SQRC<\/li><li>Frame QR<\/li><\/ul>\n","protected":false},"excerpt":{"rendered":"<p>A QR code (Quick response code) is a genre of the two-dimensional bar-code (or matrix bar-code), It was designed in 1994 for the automotive industry in Japan.The QR code system was invented by &#8220;Masahiro Hara&#8221; &#8230; <a title=\"What is QR Code?\" class=\"read-more\" href=\"https:\/\/whatisandhowto.com\/what-is-qr-code\/\" aria-label=\"More on What is QR Code?\">Read more<\/a><\/p>\n","protected":false},"author":3,"featured_media":427,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6],"tags":[312,309,306,307,308,311,310],"_links":{"self":[{"href":"https:\/\/whatisandhowto.com\/wp-json\/wp\/v2\/posts\/426"}],"collection":[{"href":"https:\/\/whatisandhowto.com\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/whatisandhowto.com\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/whatisandhowto.com\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/whatisandhowto.com\/wp-json\/wp\/v2\/comments?post=426"}],"version-history":[{"count":0,"href":"https:\/\/whatisandhowto.com\/wp-json\/wp\/v2\/posts\/426\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/whatisandhowto.com\/wp-json\/wp\/v2\/media\/427"}],"wp:attachment":[{"href":"https:\/\/whatisandhowto.com\/wp-json\/wp\/v2\/media?parent=426"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/whatisandhowto.com\/wp-json\/wp\/v2\/categories?post=426"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/whatisandhowto.com\/wp-json\/wp\/v2\/tags?post=426"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
