The entire thing measures just 1.98 square micrometers, with each individual pixel coming in at 49 nanometers across, smaller than most bacteria and roughly three times more compact than the previous record holder.<\/p>\n<p><span id=\"more-239107\"\/><br \/><iframe title=\"World&#039;s smallest QR code | Guinness World Records\" width=\"640\" height=\"360\" src=\"https:\/\/www.youtube.com\/embed\/JohNlUDp6aY?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><noscript><iframe title=\"World&#039;s smallest QR code | Guinness World Records\" width=\"640\" height=\"360\" src=\"https:\/\/www.youtube.com\/embed\/JohNlUDp6aY?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/noscript><br \/>The code was milled into an ultra-thin ceramic film using a focused ion beam, the same technique already used in industry to coat cutting tools against extreme heat and pressure. The material is chemically stable enough that the atoms stay exactly where they are placed rather than drifting and blurring the detail over time. Independent experts at the University of Vienna verified the results, the data was read multiple times without damaging the structure, and Guinness World Records gave it the official nod.<\/p>\n<p>\n<img decoding=\"async\" src=\"https:\/\/images.techeblog.com\/wp-content\/uploads\/2026\/03\/30205236\/worlds-smallest-qr-code-guinness-world-records-1.jpg\" alt=\"World's Smallest QR Code Guinness World Records\" width=\"1280\" height=\"720\"\/><br \/>\nWhat makes the achievement significant beyond the size record is the durability. Most digital storage degrades within years or decades, but ceramic based storage of this kind has the potential to last centuries without any power supply or climate control required. The comparison the researchers reach for is stone inscriptions from antiquity, still legible thousands of years later, and the underlying principle is not far off.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/images.techeblog.com\/wp-content\/uploads\/2026\/03\/30205241\/worlds-smallest-qr-code-guinness-world-records-2.jpg\" alt=\"World's Smallest QR Code Guinness World Records\" width=\"1280\" height=\"720\"\/><br \/>The practical implications are considerable, as the same approach could theoretically fit over two terabytes of data onto a single A4 sheet. The team is now focused on refining the engraving process and working toward larger scale production, with the longer term goal of building a permanent archive capable of preserving information indefinitely without ongoing maintenance.<br \/><span>[Source]<\/span><\/p>\n<\/p><\/div>\n<p><!-- .post-content --><\/p>\n<div class=\"author-box\">\n<div class=\"image\"><img alt=\"\" src=\"https:\/\/secure.gravatar.com\/avatar\/a3bdefee1518cfd8cae23d5f54c6867c0e89d466c01b67a0f6b4fb43536234f8?s=82&amp;r=g\" srcset=\"https:\/\/secure.gravatar.com\/avatar\/a3bdefee1518cfd8cae23d5f54c6867c0e89d466c01b67a0f6b4fb43536234f8?s=164&amp;r=g 2x\" class=\"avatar avatar-82 photo\" height=\"82\" width=\"82\" loading=\"lazy\" decoding=\"async\"\/><\/div>\n<div class=\"content\">\n<p>\t\t\t<span class=\"author\"><br \/>\n\t\t\t\t<span>Author<\/span><br \/>\n\t\t\t\tJackson Chung\t\t\t<\/span><\/p>\n<p class=\"text author-bio\">A technology, gadget and video game enthusiast that loves covering the latest industry news.
