Thailand's Immigration Bureau has been piloting a new mobile application, Thailand Immigration Management (THIM), since June 2026, with the official launch scheduled for August 2026. The app lets foreign travellers scan their passport, enter accommodation and flight details and generate their Thailand Digital Arrival Card (TDAC) from a phone — the same arrival card that has been mandatory for every foreign visitor since May 2025.
What the THIM app does
- •Passport scan: photograph the passport and the app reads name, number, nationality and dates automatically.
- •Same TDAC questions: accommodation in Thailand, flight, arrival date and purpose of visit — identical to the web form.
- •Groups of up to 10: one person can register a family or group in a single session; individual registration takes about three minutes.
- •Saved profile: on the next trip you only update flight and arrival date.
- •iOS and Android; English, Russian, Japanese and Chinese at launch, with more languages announced.
Do I need THIM instead of the TDAC?
No. THIM is a new channel for the same requirement, not a second form. During the pilot the Immigration Bureau has said travellers may use either the app or the existing TDAC web portal, and both produce the same QR code that is checked at the immigration counter or e-Gate. As of 17 August 2026 the Bureau has not announced a shutdown of the web portal; we will update this article if that changes. If you have already filed your TDAC for an upcoming trip, you do not need to install anything.
What this means for TDAC.info customers
Nothing changes for travellers who file with our assisted service: your TDAC is submitted through the official channel and you receive the same QR code by email. If you prefer to use the app yourself, our field-by-field TDAC guide and the how-to-fill walkthrough apply unchanged, because the questions are identical — the passport-name, occupation and address rules that cause most rejections are the same in the app.
