Reliable QR Code right now
High quality QR code Maker? QRCode Orderific also has no limitations. All generated QR codes will work forever, do not expire and have no scanning limits like you see at other commercial QR code generators. The created QR codes are static so the only limitation is that you can’t edit the QR code again. Put a custom brand on your QR code. With QRCode Orderific it is very simple and straightforward to add a logo to your QR Code. The QR codes are still readable. Every QR code can have an error correction up to 30%. This means 30% of the QR code (excluding the corner elements) can be removed and the QR code is still working. We can put a logo image on the QR code that covers up to 30%. Most free QR code makers only allow creating QR codes in low resolutions and do not offer vector formats. Use the offered vector formats to print QR Codes in huge resolutions without losing quality. We recommend the .svg format for further editing. The offered .pdf and .eps formats only support classic QR codes without the design and logo options. Read more information at QR code Generator free.
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.
As a result of the growing demand for technology to lighten the burden on supermarket cashiers, a POS system was created. It was basically the newborn baby version of a Barcode that allowed for the scanning of individual items to be registered by a computer. Despite this effort, however, this still wasn’t enough. Supermarkets then faced another obstacle: Barcodes could only store up to around 20 alphanumeric characters of information and functioned with one dimension (one direction of coding). The invention of the QR Code can be contributed to the DENSO WAVE and their lead developer Masahiro Hara. They were contacted by supermarkets who realized the limits of these Barcodes and sought a way to make them more versatile and contain more information through the development of a 2-D Code (two directions of coding).

As American dissatisfaction with waiting in line grew throughout the 50s and 60s, IBM set to work in the early 1970s to revisit the earlier patented technology. And IBM, in coordination with the grocery industry, developed the vertically-aligned UPC barcode we know today. The idea was to create a universal system of product identification and processing. A system that didn’t rely on manually entering numbers anywhere, but on fast optical scanning. Point-of-sale (POS) systems and scanners were required to scan and process the new UPC barcodes. Those were sold and distributed by IBM. By the late 1970s, checkout lines had sped up 40%. Throughout the 80s, thousands upon thousands of grocery and retail stores adopted the technology. By the 2000s, the barcode business had a value of around $17 billion. Billions of items are now scanned every day in every industry across the world.
