Snack machine, add a touch screen?

Question

Do it yourself

Greetings friends.
I have a snack machine, but as with all devices, you need to dial the product code on it.
Question: Is it possible to replace the touch dial with a touch dial? I chose a product photo on the screen and he gave it out after payment.
And the cost of such alteration is interesting

Answer 1

can. Raspberry + screen (7") + any small things will cost about 10k. Plus write a program, plus screw it all into the device - this already depends on the greed of the programmer and on the complexity of "embedding" (well, and on your location).
Yes, this is not vandal-resistant touchscreen!
