Thailand's THIM app: what it changes for TDAC, OTAs and airlines

Thailand's Immigration Bureau officially launched the THIM app as a second channel for the free Thailand Digital Arrival Card (TDAC), with visa-on-arrival and extensions planned. What OTAs and airlines should update.

Thailand's Immigration Bureau (Royal Thai Police) held the official launch of the THIM (Thai Immigration) application in early October 2026. The app has been downloadable on the App Store, Google Play, and Huawei AppGallery since 1 August 2026. The Bureau reports 600,000+ downloads and 580,000+ users so far.

This note is for OTAs and airlines selling Thailand. It is not legal advice.

What THIM does today

It is an additional channel to submit the Thailand Digital Arrival Card (TDAC). The TDAC website remains the official system.
It includes an "Explore Thailand" section with partner privileges.
It uses NFC passport-chip reading, liveness detection, and face comparison for identity verification, per the Bureau.

What is planned

The Immigration Bureau says it plans to add queue booking, a certificate of stay, visa extension, 90-day reporting, and visa on arrival at authorised checkpoints. No dates were given. Treat these as a roadmap. They are not current rules.

What stays the same

TDAC is still required under the current rules and is free on the official site (tdac.immigration.go.th). THIM is an extra channel. It is not a new requirement.
Visa exemption, visa, and e-visa rules are unchanged by THIM.

Why it matters for OTAs and airlines

01

Official-channel hygiene. With two official channels (the website and THIM), the space for look-alike paid "TDAC" sites grows. Point travelers only to tdac.immigration.go.th or the THIM app published by the Thai Immigration Bureau.

02

Selfie and NFC steps are a drop-off risk. THIM's NFC and liveness flow is stronger security, and it creates failure points: older phones without NFC, poor lighting. Keep the website TDAC link as the fallback in pre-trip messaging. The usual capture failures are in selfie and liveness failures.

03

Visa on arrival in the app would change VoA flows. If VoA moves into THIM, OTAs selling to VoA nationalities will need to update pre-trip guidance. Watch for an official date.

04

Messaging timing. Keep TDAC reminders in the final days before arrival, separate from any e-visa step.

How SimpleVisa helps

SimpleVisa monitors official Thai immigration channels and updates the requirement logic and traveler messaging in partner flows when a rule or channel changes. Talk to sales.

Watch Thailand

Coverage alerts send one email per rule change for the destinations you pick, from the partner console. Systems can take the same events as webhooks; the shape is in the developer docs. The live requirement for any passport is always in the requirements checker.
