There is nothing in the video to show that this is a voting machine, or at a polling place, or occurring today. It could be an image on a computer screen, easily generated, with an animation showing the checkmark appearing as the user is touching the screen on his computer.
That said, the background noise adds some realism.
Here is where it’s all happening. Voter is still standing behind his story. His comments are below.

EDIT: There is a lot of speculation that the footage is edited. I’m not a video guy, but if it’s possible to prove whether a video has been altered or not, I will GLADLY provide the raw footage to anyone who is willing to do so. The jumping frames are a result of the shitty camera app on my Android phone, nothing more.
EDIT2: I have been contacted by NBC Universal and BBC News.
