Picket up my card yesterday, went to Lowu today.
I went to to one of the counters with the e-registration sign - to be told to go to one at the far left.
There all 10 fingers where scanned - and I could go through (and was told to go to the 2nd floor)
Means you are already passt immigration - and past customs!
Before you leave the the building, at the information desk on the left, you go left and go up, basically follow the signs.
Get a number from the vending machine (even if nobody is waiting) - and then it takes a few Minutes.
There was a pretty long lecture with it, but I didn't understood anything other than not today.
Upon exit I went to the Special Lane for manual processing. But card didn't scan. Then to the next counter - still didn't scan (but now 4 staff), then to another counter (closer to the passport people - allthewhile I got watched by a waiting audience hoping for an arrest). Counter #3 also didn't work. And then I had to proceed to an unmanned counter that was open specially for me. After a Minute or so I could go through.
Will most likely go another time later this week for a new try.
