Thank you, that looks almost exactly like what I was looking for. I wish they took care of the merchant services as well like Square, but at least they work with enough processors that I'm sure at least one of them will be a good match for me.

That's correct, I want to use someone elses hardware with software I want to write. I guess basically I'm looking for someone that is just like square except instead of them writing the POS interface they were like Stripe where they provide the API and not the UI.
