USE CASE #1: QR Codes on a Webpage in general and QR Codes on DokoDare in particular

Why a QR Code on a webpage?
Many people say, that they don't understand why on earth someone should put a QR Code on a website as you are already have it before your eyes.

Well, in general, you are not glued to your PC screen 24 hours and so it makes a lot of sense to scan the QR Code and take the webpage with you when you are leaving the "big screen". Normally you also have more idle time when on the move than before a PC, so a QR Code helps you also to bookmark interesting things which cannot be read right now - as you are probably working.
Also the webpage and the mobile version can significantly diverge in what they offer as both screens have different advantages and disadvantages.

In the case of DokoDare this is even more true. The normal use case of going somewhere unknown was to 1) print the address with phone numbers and all 2) to go to map service 3) to print the map and note down phone numbers 4) to finally head to the place.
Now you find a place on DokoDare (example (web version not yet open to the public)), you scan the QR Code and you have everything with you - address, phone number, map, additional information. And even better, you have not only the place you are going to, but you also see nearby places (like nearest bus or tram station, a café where to wait when you are too early etc.)

Let me know if that has helped you or if you have something to add to it in the comments.
