After reviewing the ATM API developed for ICG, I noticed that it uses a point of sale system which is rather innovative by itself. I'm surprised that Incognito coin is selling at such a low price after development and incorporation of ATMs, mobile wallets, web wallets, brain app, and new wallet features. User adoption seems to be increasing.
That is correct. A point of sale system was indeed used in the ICG ATM API allowing for quick transactions. The Incognito Coin team is currently seeking for more ATM providers as the existing API should allow for quick integration and broaden the potential user-base.
That sounds interesting. It could also be possible to extend the point-of-sale system beyond web merchants and ATMs and implement it in a form of marketplace paired against ICG. There's numerous possibilities as to how the existing API could be further expanded, but for now I think that increasing the amount of ATM partnerships would be ideal.
