I didn’t need a visa so I didn’t need on I came on the 30 day visa exemption stamp…they look at the rest of the documents at least 3x before you get to the “laptop” station…it took me I believe 30 min to get to the “laptop” station they do have chairs for you to sit in
from what I observed they don’t scan the QR code at all…I have no idea what they are looking at, they are using a laptop so I’m guessing they are typing in your passport number and name to verify it on thaipass
I just went through with 2 Thaipass QR codes for different dates one printed one electronic and all they looked at was the printed one…but since I had 2 I really don’t know if they verified the electronic one but I was not going to be denied entry over paperwork
