Hmm... interesting but the prices are high.
I have a POS sitting on my desk now that sells for $250US - so your upfront is lower. The chip card cost is very high. It should be around $3US.
This one doesn't have a 3% fee or a 5% conversion cost.
I think you've missed the point on what will make the "killer app" of POS systems.
For the right price I'll sell you one of my POS units and the code to make it work For an even better price I can just sell you the whole project and retire early.
