I jusr went thru immigration in GIG an hour ago, and there is no fingerprinting taking place, nor is any equipment visible in the PF kiosks. Landed on UA129.
Forgot to add that if your visa requires fingerprints (I have a permanent resident visa VIPER) the PF will take all your fingerprints the old school way (INK) as well as electronically. I forgot how messy that was.......heh.
