All of us just can’t but see QR codes everywhere we go – on the big-boards, in the subway, in supermarkets, stores, on buses, in magazines etc. What are these cute little things which look like something totally strange? So, nothing extra-special here in fact.
QR Codes, where QR is an abbreviation of Quick Response, imply two-dimensional or matrix code which ware primarily developed for automotive industry. They were invented in Japan in 1994 to track vehicles during the process of manufacturing. Nowadays they are being used in a great variety of fields and industries.Such codes consist of square dots (black modules) which are arranged in a square pattern on white background. The information which is encoded can be of 4 data modes:
How actually the QR Code works? In order to read the encoded data you will need a device with correct reader application which can scan the image after you take the shot of it with a camera. This app will decode the info displaying text, contact information and other data. Also QR Codes may be decoded in Android operating system via Google application or third-party barcode scanners. But, of course, all modern smartphones can decode the QR Codes with the help of certain applications developed specifically for this purpose.
Let’s make it clear where QR Codes are used nowadays. You may be surprised by the number of areas for using it:
1. Cards, posters, outdoor advertising with the encoded message or wishes
2. Discounts – you can show the Code from your smartphone for it to be scanned in the store, and get a discount
3. Link for downloading music, files, videos, playbills. You can not only download something on the Internet but also use a certain device which will turn on your favorite karaoke melodies after QR Code encoding

Apart from it, QR Codes are being used in many other areas which diversity grows regularly. But the last thing I’d like to mention in this post is that QR Codes can be not only black-and-white.
