Honestly, if implanting a chip in my arm meant I could just walk through immigration/customs/check-in without carrying anything I'd do it. I have Global Entry so things are already pretty good but I'd give them anything to ease the process. And it's not like I'm going to lose my arm in the normal run of play so that's even better than my passport.
