The new form of getting information, are the QR-codes. QR means quick response. What can be the use of a QR-code?
The QR-code is a two-dimensional (2D) bar code and was for the first time designed in Japan, for the automotive industry. The huge advantage of this type of bar code is that you can get the information faster then before. For example, in 2006, the world champion needed 42 seconds to tip an SMS with 160 signs. An URL address can contain 250 signs. So the world champion will need more than a minute to tip the URL-adress into the browser. So when you scan the QR-code, a program analyses it and decodes the information faster than every human being.
What kind of information can the QR-code contain?
Several informations can be transformed into a QR-code: a telephone number, an SMS, a link, a text or a Vcard with name, telephone number and e-mail address.
For the marketing, this instrument can be very useful, because the costumer can get rapidly information or it can be used for a marketing campaign. The possibility exists to design a QR-code with the logo and the colors of the firm, so that it can be recognized easily. You can put the code on promotional items like shirts or post-it’s.
The possibility to create a QR-code exists for everyone and there are also some websites where this service is free.
You only need a phone with a camera, which is necessary for the scan of the code and it has to be compatible with Java. A QR-code-scanner application is only necessary, but there exist some free applications which are very good.
