Build a bridge to your content QR codes can link to pretty much any content on the web. They provide an instant jumping-off point for your customers – and potential customers – to find and view anything you want to put in front of them. One quick scan with any modern smartphone and users go directly to branded content such as a website, a simple text message or styled HTML/CSS page, create a Tweet, a Facebook "Like" button, your contact information (VCARD), or several different types of files you provide such as images, PDFs, or videos. We're adding different types of allowed content types every month! Better data drives better decisionsQR Code Printing Guidelines & Best Practices 32 × 32 mm or 1.25 × 1.25 inches, excluding quiet zone (the white space included around the QR Code in the EPS) is the minimum size that guarantees that ALL camera phones on the market can properly read the QR Code. 26 × 26 mm or roughly 1 square inch, excluding quiet zone covers 90% of the phones on the market. - OUR CURRENT RECOMMENDATION The latest camera models, which have improved macro capabilities, can deal with QR Codes that are less than 10 mm (0.4 in) wide and high. For example, an iPhone 4 will be able to scan this size, but an iPhone 2/3.x with 2.0 megapixel camera and no autofocus may not. For good reader accuracy good contrast between the background and the bar color itself is very important. The bar code should have a dark color on a light background.
