Most people have smart phones (except me and mine) and they're using them at Walmart. Walmart and others are integrating such systems because they know it's the future. Did you see how easy it was to pay the vending machine? Honestly, I think Evolution is for online purchases, I don't think it'll do much for face to face purchases which are already extremely easy.
My mom worked in a bank for 30 years and she simply cannot grasp cryptos.
The vending machine is EASY if you have cryptos under your belt. Evo is absolutely all about face to face interaction as well, in fact, that is the whole plan behind it. No pub/priv keys to worry about, no long strings of alphanumeric gibberish. Simple to use, day to day experience, with an underlying cryptographic powerhouse fueling it.
Why did Bitcoin explode?
Because of Silk Road.
It created a solution to a huge problem (despite illegal in nature) that drove thousands to climb the mountains of difficulty of attaining BTC to buy their goods. There was a serious motivation behind the learning curve. The hoops these guys had to jump through was worth the trouble to them.
If you can sell a car for half a price with crypto's, done deal.
But integrating Dash into PoS, or creating machines that talk blockchain is nothing out of this world. It hasn't been done because it's simply not profitable in the vending world. Heck, here at work Management complains the electricity our vending uses is possibly not worth the trouble of dealing with the company providing the re-stocking of the crappy goods it contains - and this is with plain old FIAT.
Don't get me wrong, I love the idea. Not so much the vast amount of Dash needed for something any company can do in a week with a dedicated team of professionals when the time comes.
