Best QR Code Generator? Set the pixel resolution of your QR code with the slider. Click the “Create QR Code”-button to see your qr code preview. Please make sure your QR code is working correctly by scanning the preview with your QR Code scanner. Use a high resolution setting if you want to get a png code with print quality. Now you can download the image files for your QR code as .png or .svg, .pdf, .eps vector graphic. If you want a vector format with the complete design please choose .svg. SVG is working in software like Adobe Illustrator or Inkscape. The logo and design settings currently only work for .png and .svg files. See additional information on QR Code.

If a position detection pattern is used in a code and there is a similar-looking mark nearby, the code reader may mistake it for the position detection patterns. To avoid this type of erroneous reading, their position detection patterns had to be truly unique. After mulling over this problem thoroughly, they decided to do an exhaustive survey of the ratio of white to black areas in pictures and symbols printed on fliers, magazines, cardboard boxes and so on after reducing them to patterns with black and white areas. They continued the task of surveying innumerable examples of printed matter all day long for days on end. Eventually, they came up with the least used ratio of black and white areas on printed matter. This ratio was 1:1:3:1:1. This was how the widths of the black and white areas in the position detection patterns were decided upon. In this way, a contrivance was created through which the orientation of their code could be determined regardless of the angle of scanning, which could be any angle out of 360°, by searching for this unique ratio.

Like the development of many technologies, QR Codes were created out of necessity. QR Codes actually started out as Barcodes with their typical purpose: for supermarkets. In the 1960s, Japan was experiencing a wave of economic growth. Supermarkets expanded from selling just food items to adding in clothing and a versatile range of other commodities. So, they basically realized that they needed a way to keep track of everything. Before Barcodes existed, cashiers had to manually enter individual items (can you imagine?!), which of course took ages. Due to the health issues created as a result of these heavily repeated actions like carpal tunnel syndrome, supermarket managers knew they needed to find a solution.

QR codes are the natural evolution of traditional UPC barcodes. They’re also improvements over barcodes in every aspect. And to understand why they’re so much better, we must summon the past. QR codes were invented for a reason-by people with unique constraints and goals. And they’re a product of their time, with its distinctive status quos and obstacles. Come, let us rummage through the reams of QR code history and discover how the QR code came to be its lovely self.
