It's the "for payments" version of all those "but on a screen" patents that people here hate on so much. Prior work includes but is not limited to Facebook tag suggestions, and and just about everything done in facial recognition on any laptop in the world.
I'm afraid that I (and surely many others on Hacker News as well) will not be cheering you on. It's pretty much the definition of something I do not want to be patentable.
I understand it will probably not be possible to convince you to change your mind, so I won't insult you by trying. However, keep in mind that your stance really is diametrically opposed to many groups who do not want software patents.
