Is it necessary to scan the TDAC QR code upon arrival in Thailand?

I arrived today having already completed the TDAC, I was emailed the qr code which I assume would be scanned. The I.O. said it was already on record and no need to scan it ?
Answer summary
Upon arrival in Thailand, the TDAC (Thai Digital Application for Confirmation) QR code does not always need to be scanned by immigration officers, as they can access the necessary information by simply entering the passport details into their system. However, having the QR code printed out as a backup is advisable, as it can provide an extra level of confirmation if required. Some visitors noted that their QR code was not scanned and others suggested saving it as a screenshot for future reference, especially if any immigration services or extensions are needed later.

I will be arriving in Thailand on a 90 day non O visa. I assume I still need to fill out a TDAC form?

remember it's free to fill in any time between 72hrs and time of arrival. Only boxes with asterix unless specifically relevant to you. Happy travels!

it's an arrival card. If you are going to arrive, you fill it in. It's nothing to do with visas.

Been to do a TM30, now saying as I had only left Thailand for a few days and returned to the same address not required now, it was before.

Being the ever pessimist Thailand we’re going introduce a 300 baht arrival tax which has been put on hold. I bet once the system has been in place for a bit they will add a fee of 300 baht the same as you do before going to The States.

It seems such a hit and miss subject on whether it's required.

The agent I asked would normally charge 500 baht to do the TM30, she could have said yes you do and took 500baht from me. Before anyone says it’s free which I know but it’s few hours out my life that’s why I use an agent.

Ok. I was told the same by the agent but double checked at immigration and they said it was required and then I know people who were told the opposite.

As others have mentioned it's already in their system, the print out and QR code are a backup, because Thai IT. Also you might need it for immigration services in the future such as an extension.

Yes just save it as screenshot just in case, never needed it though

True. Didn’t need to scan mine either!

Yes, that is correct. It comes up on their screen when they scan your passport. It's still good to have it because they can ask you for it.

Neither have I, but the IO can ask for it if.

It's all online and they already have it. But it's an extra level of confirmation in case they require it. I never rely on technology and printed mine.

so you killed a tree for nothing? Absolutely no requirement to print it out.

@Jack *******
I was asked for a printed ticket so yes, printing was useful. Lost phone/broken phone/ no signal. . So instead of you wasting time whinging about "killing trees" try some commonsense.

lol. Looks like abusing women on line is your hobby. What a vile creature you are. All because I printed my ticket as requested by the airline. . And printed my TDAC same time. How pathetic. I guess you have mental issues around women who don't obey your demands so making stupid childish namecalling comments makes you feel like a big man. Lol. Compensating for something? Fyi I've a home in Thailand and am far from skint. 😆

I've just flown in recently and was asked for the printout. Your hysteria over this is bizarre. Pathetic name calling over someone saying they printed a piece of paper. You're just a weird guy looking for an excuse to be abusive.

I think there is a bit of confusion as some people like me think you have to show the qr code at immigration.

@James **************
you don't have to show the QR code if the Immigration officer sees that you fulfilled the TDAC, when he scan in your passport. That's why they won't ask you . . avoiding extra surveillance

as always they could ask you for it..that's Thailand. Best practice is to be prepared.
