A few weeks ago, I came through LA customs and other than a sign saying a digital fingerprint would be taken for foreign nationals entering the US, there wasn't a big deal still. People were coming in, the lines were moving at the same speed as they always have and no one was grumbling about any extra inconveniences.
So has anyone here had to deal with it? I'd be more interested in hearing from someone who has had to be digitally fingerprinted than anyone up in arms over something they haven't experienced or that that have first- (or even second-)hand knowledge of.
