Anyone else seen the new US VISIT exit machines?

I can swear that they weren't there in SFO 2 weeks ago, but yesterday afternoon after passing through security (I won't digress to say how annoying this is, or how useless they are as I had completely forgotten I had some empty bullet shells in my coat pocket, not that they noticed), I started seeing some new US VISIT kiosk machines, dotted around the place in pairs, and some at the top of each gate area. No indication had been given to me that I needed to use them, but being inquisitve I asked, and was asked to follow the process at the machine:
scan in passport, type in flight number, left index finger scan, right index finger scan, and then a receipt is printed out.
Anyone else seen these at any other terminals?
I can scan in my receipt if anyone is interested.
Strange thing is that many people were walking past blissfully unaware, I would of thought the two atendants manning the kiosk machines would have sheperded the departing passengers through, but that would be too easy.
Thanks,
Richard
