Anyone know when they started issuing passports that meet the requirements for these machines?

Thank you for the reply, we'll give it a try next time through!

Well, we tried

Landed at Siem Reap. Directly on the left as you enter are three machines. We went to the middle one. Gentleman in front of us went through.

My wife tried her passport and couldn't get it to scan - so I tried. She had it to the left against the side so I tried in the middle of the scanner not touching either side and it went through. She then put her finger in the finger scanner and it worked and gates opened. But of course we have two children so she didn't go through. Scanned first child's passport and it went through. Scanned his finger - wouldn't take. Had to scan the passport again. Again finger wouldn't scan. Ok, tried the other child. Same results.

So I motion to a nearby immigration official (who it turns out is supposed to be monitoring these machines but is currently speaking with one of his buddies). He frowns and slowly comes over. My wife explains the children's fingers aren't scanning - he says NO BABIES! And is not happy that he now has to take my wife's passport and children and go to a booth to send them through. About the only good thing is that last time we came through got all kinds of hassles about having dual citizenship for the kids and using "the wrong passport with no stamps" (when we were using the correct passports). This time he basically wasn't even paying attention and just did whatever he needed to get rid of my wife and return to his conversation. I walked down further and went through fairly quickly.

So if you have young kids with Khmer passports you may not actually be able to use the machines.
