Completely disagree that this is trivial and doesn't require alot of money.
You are going to have to sign multi million dollar contracts with interac or whatever card processing giants exist.
I was in that business (specifically, point-of-sale processing and technology) for years; it's what led me to digital currencies, and eventually to Bitcoin as a point of interest.
I guess triviality and expense are relative, but what I'm talking about takes substantially less than $100,000 to get off the ground; you'll spend more on marketing than development. Google "white label debit card" for some good sources, e.g. Maverick, who set up branded and otherwise custom debit systems.
