QR Code (Quick Response) quick response codes, 2D codes, codes chicken, strange squares and what we hear as the name or description of this relatively new method of "communication", meaningful tattoos while younger at least know what it's for, most people are in embarrassed to scratch the ear and shrugged his shoulders when he sees strange things that adorn posters, leaflets, brochures and more.
For the QR code, it seems that traveled the path of complete obscurity to widespread use in the blink of an eye, but in reality is not so. QR Code was created in 1994, when it was for the car factory Toyota developed their branch Denso-Wave in order to facilitate the latter's car during production, but now also conquering meaningful tattoos the global market. Or is already global in exemplary use, just me capljamo for those early users of the technology. Black and white squares that appear on more and more products, all from invoices, brochures, leaflets, posters, various promotional materials, catalogs, business cards, t-shirts, products to websites. In fact, it is difficult to remember on what I have not seen QR codes. Well, I've seen tattoos QR, although this issue, or did not anyone ever think of. Nevertheless, still not as widespread as one would expect, and still is, much confusion around it. So what are QR code anyway? The best definition I've read says that this is a barcode on steroids. Actually nothing more and nothing less. It is a record that can be made to the appropriate hardware and software to translate into something we can understand. The bar code contains a record of the first type, QR, in several types, meaningful tattoos forming a smaller or larger square. Thus, there is more space for the recording of black and white fields, which means that it is possible in this manner to write more information. Usually it is a record of a web address where you can learn more on the matter, which is the QR code added. Smart, as well as less smart phones, if supported by Java are the perfect hardware for reading QR codes, but even with them we have always. Required only camera that will cover the record, and software that will record translated into a comprehensible form.
So you can almost each holder of a mobile phone to read the QR code and a mobile or public Wi-Fi connection meaningful tattoos to the Internet at home or at a later stage via your Wi-Fi network view, which you are interested in or what someone wants, that he would be interested. This means that it is a potentially very powerful technology, which would of course be wise to take advantage of the business or other purposes.
Since the matter should be only slightly familiar with before you decide to take advantage of, I will try to cover at least the most important issues, among which are, as with any other technology, also set traps. Anatomy of QR codes
Regardless of the version of QR codes is the basic form of the same, except that up to 45 x 45 is the data entered on the version of the code. In this photo, the code size of 33 x 33 and is only indicated the place where the major codes also included in this figure.
In all versions and sizes are important elements. Squares in three corners are so that the reader knows how much is a box, a small box to determine the settling and anything else you can see in the photo. That irregular black-and-white checkered flag, the data record. Black and white is not really required and can be replaced by others, but the contrast between the colors must be large enough that readers do not have this problem.
QR codes are a range of sizes and in several versions. The bigger the box, and over the objections of fields, more characters can be entered into the QR code. However, it all depends on what kind of signs, or just about numbers, whether it is for letters, you can also go for binary record. It is also important, what is the level of protection meaningful tattoos or troubleshooting. The record in the source code is in the form of osembitnih code words. There are several levels of error correction, and thus greater resistance. With increasing security while reducing the number of characters that can be recorded. meaningful tattoos
Subject is not only important meaningful tattoos for the security of data under normal use and form of QR codes, but this just makes us a little more creative use of QR codes. You can make QR code with a short recording on a large field with the highest degree of error correction in which it is possible to remove a piece of code and replace it with lettering, logos and the like, but the record is still readable.
Nevertheless, in older phones a few problems with reading QR codes. Thus, it is wise long web addresses routed meaningful tattoos through one of the servers to shorten the title of the record, such as the tinyurl.com. Shorter than the record and will be better than debugging easier, users will read your QR code.
