Looks like
these folks are working on such a thing.
Don't know whether this will be a viable product, but it looks like they are serious about it.

Both projects look pretty good but the idea is to keep it simple. Look, for example companies have tried to get the phone pay since years, and what? why? nobody wants to use "air" for transactions or to have together their financial data. People wants something physical, and human required action such as insert card, type pins, etc... Something that you can "see" actually working. Even consider that a "virtual currency" is a huge leap for traditional minds.
Also, if you want to implement something to public it should be cheap and accessible, functional, secure, but no rocket science. Look Paypal, I remember how was at the beginning for a lot of people to "publish my creditcard on internet" and now is the most reliable method of payments worldwide. The same with ebay, afraid of buying "a picture" on a web site, smoke, "how can I be sure that I'm buying something", "I don't know that person", " I can't touch or test the item". But still they work. Why? Accessibility, trust, simplicity, and most important: Everybody is using it.
If you target to "Everybody" it needs to be simple.
-A card (standard).
-A card reader to connect with your computer wallet and charge it.
-A PIN code to secure it.
-A device you can plug, identify and pay.
I don't think ANYONE would ask "How it works?"
