I didn't realize that one could use a non-epassport in these gates.
Presumably then these machines read the machine readable portion, and then print out the receipt, but DON'T check for a counterfeit passport or modified passport? The epassport machines in Europe compare the photo taken of the passenger standing in front of the machine to the chip, and then open the gate if their is a match.
I can see why they still need the human intervention, as the system is very insecure compared to the European system.
