Unlike traditional barcodes (the ones you see on products in stores), QR codes can store <strong>much more data<\/strong> and can be scanned from any direction.<\/p>\n\n\n\n<p>Think of a QR code like a <strong>digital shortcut<\/strong>. Instead of typing a long website link, phone number, or message, you simply scan the QR code and your phone instantly understands what to do.<\/p>\n\n\n\n<p>For example, a QR code can store:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A website URL<\/li>\n\n\n\n<li>Contact details<\/li>\n\n\n\n<li>Wi-Fi passwords<\/li>\n\n\n\n<li>Payment information<\/li>\n\n\n\n<li>Text messages<\/li>\n<\/ul>\n\n\n\n<p>Each small square inside the QR code is called a <strong>module<\/strong>, and together they form a pattern that represents encoded data.<\/p>\n\n\n\n<p>What makes QR codes powerful is their ability to store information in a <strong>compact and machine-readable format<\/strong>. To a human, it looks like random squares\u2014but to a scanner, it\u2019s a structured data map.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"2_How_Information_Is_Stored_Inside_a_QR_Code\"><\/span><strong>2.
