Only on the first time you have to scan all fingers, after this only 4 fingers of the right hand.

I went out on Friday morning for a meeting in Laos.  I stamped out and had to scan only 4 fingers on my right hand.  But when I stamped back in a few hours later, I had to scan both hands and thumbs, - not that it's a problem or important, just commenting ????

If they rolled that out at the main airport , you'd be starting to cue before leaving the plane

In that case you'd end up being snookered right away.
