What is QR code?

Computers are widespread, with many things that are computer, including things that we usually don't mean as computer. These computers, large and small, make small and massive tasks, run on different complexes of codes. One such code is a QR code. Given the lack of imagination of people who name computer codes, it is no surprise that this term is nothing more interesting than the quick response code. Such a code can be found today with the operation of thousands of different things, from cars to cameras. It is limited to two dimensions so you don't see a real picture. The QR code was made with the intention of decoding at very high speeds, so the third dimension was not considered necessary. It is also a relatively new code that was created in 1994 in Japan. By the way, this country still sees its most common use, although most of what they sit down is exported to the rest.

The QR code was created as a step up from the barcode. Contains data in vertical and horizontal directionech, while the barcode has only one data direction, usually vertical. The code can also match more information. It is easy to spend easily with a scanning device and has potentially double the amount of data as a barcode, it can increase the efficiency of such scanning.

Another analysis shows that the QR code can process the alphanumeric character, symbol, binary and other code types. It can hold up to 7,089 characters in one symbol. This is of course only numerical. The limit of alphanumeric characters in one QR code symbol is a decent 4 296. In addition to being denser than a binary code, it is also much smaller and shows Moore's law at work. The QR code also has error correction, and the data can be brought back to the full life, even if the symbol has been destroyed. All these features are much better than a barcode.

Telephone manufacturers in Japan began to include in their QR Code-Read-Read Software, C productsOJ makes it easier for users to store and load data more. This code also migrated to other non -traditional media, including business cards and magazines.
