Other advantages
"skip the line" cards are also useful to sleeper terrorists. All they have to do is note when their card is rejected, indicating that their "affiliations" have been noted.
As for facial recognition, a friend's uncle reported to work at a (allied) shipyard during WWII with a photo of Hitler spliced into his badge. Guards just waved him through. Never met him so I don't know how much he resembled the chancellor, but I'd have to wonder if anybody told him to shave. Yeah, robots won't be so lazy, maybe, and of course the lowest-bidder software will never be compromised.
