Homemade Reference Terminals?

Question

terminal emulator

There is a site-guide around the city (a catalog of places, enterprises, etc.)
I thought about information terminals in places where a large number of people gather.
There are ready-made terminals on the Internet, but somehow they are too expensive.
The task of the terminal is simple:
1) scrolling advertising banners in unused time.
2) by clicking on the screen launch the directory.
I don’t know what to choose (touch screen or tablet from 10")
To work with the site, what to use for such purposes:
1) Android application
2) Special site template (for example, mobile or iframe)
3) Special program?
