Why did the Immigration Officer ask for my TDAC when it's supposed to be linked to my passport?

THIM and TDAC notice
Need a clearer THIM and TDAC explanation? Read the THIM guide on thim.in.th.

Can back to Thailand today ,on a 1 year extension non o .And the IO asked to see my tdac which I had on my phone .This was weird because I thought it's always linked to your passport?
Answer summary
The user encountered a situation where they were asked by an Immigration Officer (IO) to show their TDAC on their phone upon returning to Thailand on a 1-year Non-O extension. They noted confusion since they believed the TDAC should automatically be linked to their passport. Community comments explain that while the TDAC system connects to the passport, various issues can arise due to it being a new system. Recommendations included bringing physical copies of documents, as the IOs may ask for documentation even if it's electronic.

I copy and carry everything. You just don't know what they will ask to see

They do have a copy, however the registration is that you bring a copy with you. They always have a complete manifest from every flight arrival, doesn't stop them asking for your boarding pass, also they have your hotel registrations, don't stop them from asking, because you're required to have all that to present to them on request.

If, for any reason, your TDAC doesn’t come up when they scan your passport, they ask to see your copy. They can use the TDAC number to search for it.

You probably made a small typo but they could recognize you with a quick verification.

BreezyGiraffe4639 possible because it was approved in about 10 seconds so obviously not checked

Steve Fortefyve no it was legit otherwise IO wouldn't have accepted it .But as Brandon says it's not 100% so best to have a copy

If you apply for it when you just have landed,…it’s almost impossible to get a print in the airport,…

And nowhere is it printed that you have to print it.

Michael Riddermann Munck Pedersen That's what I thought. I've never seen anywhere where it's said you need to print it out. Even the official TDAC website says you can keep a copy of the QR code on the phone.

Chris Blunt best print it. Nobody has told me I need to breath recently but I find it a good idea.

Chris Blunt so if you lose your phone or it's damaged what do you do? Printing important stuff is always recommended.

Chris Blunt how about if your battery goes as you reach the IO because the USB in your plane seat doesn't work?

Lynnette Munoz So if you lose your paper printout, what do you do? In the case of the TDAC there's nothing to show anyway. The immigration officer already has access to the data you submitted because it's liked to your passport. We're living in a digital age now. Paper is so last century.

I never print anything out these days. I've got everything backed up to the cloud and can easily recover it to another device if one gets lost.

I always print stuff. Never rely just on my phone.

It's supposed to be, but it's still a relatively new system. There can be issues at times.
