It's hard to imagine everyday life without them. You can find them in magazines, newspapers, on advertising posters and business cards. We are talking here about the square, small, machine-readable QR codes, which were developed in 1994 by the Japanese Masahiro and his team for Denso Wave, an automotive supplier. Since then, the QR code has enjoyed an unparalleled success story, without which it is impossible to imagine logistics, mobile data processing or advertising. Because never before has it been possible to pack so much data, such as Internet addresses and other information, so easily into a small code that is digitally readable. The QR code thus stands for efficient data processing. While the well-known bar codes can only store 13 numbers, QR codes can already store 4000 alphanumeric characters (numbers, letters, signs).
In addition to their use in industry, they also bring some convenience to everyday life, for example on advertising posters and newspapers. Long Internet addresses no longer have to be laboriously typed in to get to the respective Internet page, but the dark dots and dashes can simply be scanned with the appropriate software. This can be done with a notebook, PC or smartphone. Two thirds of Germans do not yet have a smartphone, but the number of smartphone users is growing all the time. With the number of smartphone users, QR codes will also be used more and more in everyday life.QR codes offer a lot of convenience, even for private individualsIn the future, more and more QR codes will appear next to contact details on business cards. Instead of texting to enter a sweepstakes as before, in the future people will just scan the QR code with their smartphone and then send it. Geodata can even be stored in a QR code, which can then be used to display a holiday hotel on Google Maps, for example.
If you want to contact a company hotline in the future, you no longer have to type the phone number into your smartphone, but you can use the number stored in the QR code directly on your smartphone. Since QR codes can be saved as GIF, PNG, JPEG or TIFF, they can be used in a variety of ways. In the near future, it will no longer be possible to do without QR codes. Online shops, small retailers or companies will also have to offer their customers the use of QR codes in order to remain in contact with them or to remain in business. Entering phone numbers or URLs by hand will then be considered too cumbersome. These codes can be printed on business cards of shops or companies, on promotional items, posters or bumper stickers. One will have to adapt to the new market realities and practical and convenient these QR codes are indeed.
