I created an account to share this idea (and a few mockups). This is something that even Bitcoin has failed to do very well. Let me explain:
So many Point-Of-Sale Systems cost thousands of dollars. Have you guys ever heard of Square? Do you know why so many people don't mind paying a higher percentage for credit card processing? I mean, why pay more right? To them, Square is better value. Square offers a complete POS system - for free. What I mean by that, is - you can process cash, check, AND credit cards (using square). Square figured something out - they spend money to create this great product (for free) so that people use it! When people use it, they also use square. Even if your business only ever processes 1 credit card transaction a year, you did that ONE transaction with them.
What Monero needs (and hear me out here) is a POS system that is designed as greatly as it's currency - and is as functional as any other POS system out there. Yes, it needs to be able to process Monero payments, but that wont be the draw to the average person. But here's how you make Monero grow - imagine this scenario.
Monero's development team creates a great, functional, user-friendly POS system. It processes cash, check, credit card, and XMR. Many merchants will pick this software up because it is functional and user-friendly, and free. They will use this to process cash, check, and credit card payments mostly. Likely, they won't even care that it processes XMR transactions. But here's the kicker - now you have TONS of merchants that are ABLE to process Monero. It's like the trojan horse from history guys! The more merchants you have that can process XMR, the more people will buy and spend it. The stronger the network will become! This is really what is stopping any cryptocurrency from getting big.
BitPay started to do it with Bitcoin. They really have a nice POS, but it ONLY processes Bitcoin. People that aren't interested in Bitcoin can't use it. You need to make a POS system that people will use - even if they don't give a shit about Monero. Then, once it has a big place in the market, you start telling all those merchants how they can avoid processing fees by using Monero (And they don't even have to change a thing!) and then you've got their ear, and they're seriously listening.
Some companies have made it easy to use Bitcoin - and that WORKS for people that are interested in accepting it. What I'm proposing, is making it easy for people to use normal payment method and include Monero. The all-in-one, plug-n-play. Who could resist?
Sidenote: I believe square has an API you can tap into to make this new POS process credit cards. Cash and check are fairly simple - it's basically a records keeper at that point. But you really need to add some great features to this. I know that Monero needs a GUI wallet first. I know that it will be a huge undertaking and take precious time away from the development of the currency - but I guarantee that the first cryptocurrency to do this right, will skyrocket into the mainstream.
Here are the mockups (I'm not a professional designer) I spent probably 10 minutes on the first screen - then less time on 2nd, and even less time on 3rd. You get the point. If you give the average business person every reason to use this POS system (It's free, fully functional, runs on cheap Android tablets, easy to use) then they will use it! The trick is that it comes pre-bundled with the ability to process XMR payments. Let's say you get 1000 users on this POS system...that's 1000 merchants that are able to accept XMR and they didn't take any convincing.
