So you're just as stuck with this as the rest of us? I'd assume you couldn't move forward with this POS system without the coino cards right?
Well, not exactly. See... I don't think there ever were "Coino cards" like the roadmap promised. I mean it sounded good and its somewhat where I got the idea to use Coino for the POS machine... but the dev's coino cards don't exist. They really can't as they explained them. They were to be magic debit cards based in Germany that just happen to work everywhere in the world. That isn't possible. You can't even take a debit card from Canada to the USA and have it work, much less one from overseas.
I wish they had never listed it as part of the roadmap. It only confuses matters. Its almost worth switching the POS project over to a different coin just to get away from it!
I have a stack of Coino Cards sitting beside me now, but they have nothing to do with the Dev and their roadmap. They are cards we created to work with our machine. They don't work anywhere but our machines and never will. There is no magic in them, they are just cards that contain either a magstrip that equates to a stored private key or a chipcard that holds an actual private key.
The POS machine just gets that information to the backend server which then does the transactions on (or off) the blockchain.
The simplest way to consider the POS is as a mobile wallet that only holds the keys as long as the card is inserted. It is PCI compliant in that if you attempt to disassemble the unit to modify it / hack it to insert something to read those keys as they pass through, it destroys the shared key and can no longer communicate with the server.
Thats the same as modern day Visa and Mastercard POS machines. If you mess with them, they don't work anymore.
It would be simplest if the old dev simply disappeared and didn't come back. If they do, they will no doubt lie some more about their idea of "coino cards" that don't exist. That will only further confuse matters.
I did try several times to talk with the dev about the project. I wanted their blessing and wanted them on board. I thought it would be a nice way for them to deliver on their roadmap. But, they have never responded to any of my attempts. The backend server is up and running and processing transactions without any input from them.
If there is never any input from the dev again... it won't affect the project.
Any coin that offers the low transaction time that Coino does would be ideal for the POS project. Coino just happens to be the one I picked back when it looked like it was going someplace. Now that its dead in the water, it just makes getting more Coino a lot cheaper to play around with the project. I do regret when we purchased $500 of coino to have a pile to play with as we work on this project. But that is a drop in the bucket compared to the equipment investment!
If our project takes off... and big if... stays using Coino, it would no doubt add value back into Coino.
There is already a similar project that does this with Bitcoin. The idea isn't really new. Its about doing it faster and cheaper while also making the equipment good for something other than digital currency. I believe doing those three things better than the original POS project will make this a winner.
