I feel it's less a question of open source than a question of open standards. Plus some legislation that enables everyone who can prove they can reliably provide this service to have access.
I think the software is of secondary importance here. And even if it is open source there would be hurdles to get the (probably) reqired certificates.
My guess is that the best chance is to lobby the EU or US for this kind of standard. If one of then could be convicted to implement such an open standard payment system then others might follow.
The success chance of lobbing the EU or US is of course probably low and that might also be the answer to the questio.
