Thai immigration service launches THIM app to shorten queues and soon allow you to extend your visa online.

The new app is primarily intended to bring convenience to frequent travelers in Thailand. Those who currently sigh at the thought of long lines after a night flight may soon receive faster clarification at the immigration counter. But the plans for expansions are particularly interesting, such as online visa extensions and a digital 90-day report.

THIM stands for Thailand Immigration Management System. The app was developed by Digital Identity Co., Ltd. in collaboration with the Thai Immigration Bureau. The system runs on the infrastructure of Amazon Web Services in the AWS Asia Pacific region in Bangkok. This ensures that traveler data remains within the country's borders in accordance with Thai law.

From paper forms to digital arrival

The Thai immigration service processes an estimated 30 to 33 million international arrivals annually. Every visitor must provide personal and travel details upon entry. According to Thailand, this is necessary for national security.

Until mid-2025, this was primarily done using paper forms. This was followed by the Thailand Digital Arrival Card, the TDAC. This web form made pre-registration possible via a QR code or a special website. Nevertheless, travelers still had to re-enter their full details for every new trip. This continued to cause frustration and wasted time.

THIM must make registration faster

THIM aims to lower that barrier. Travelers register once in the app. In doing so, the system scans the passport using AI-driven optical character recognition. The app reads three data layers: the machine-readable zone, the biographical page, and the embedded chip.

On subsequent trips, visitors only need to update a few fields. As a result, processing time should decrease to approximately one to two minutes. When the traveler presents their passport at the immigration counter, the officer immediately sees that the digital registration has been completed. Consulting a separate QR code is then no longer necessary.

According to the immigration service, safety remains central.

The announcement was made during the AWS Summit 2026 in Bangkok. High-ranking officials emphasized there that faster processing must not come at the expense of border security.

Police Major General Pratya Prasarnsuk, Deputy Commissioner of the Immigration Office, called it a balance that Thailand must maintain. “The Thai immigration system processes approximately 30 million international tourists annually, and it is our responsibility to ensure that the experience of every traveler at our borders reflects the modern, welcoming nation that we are,” he said. “By embracing cloud technology, we have significantly reduced processing times while simultaneously strengthening our national security.”

Data remains within Thailand

An important reason for building the app on the AWS region in Thailand is the obligation to keep personal data within Thailand. This complies with Thai law and is intended to increase confidence in the system.

The technical foundation rests on three pillars: AI-assisted document verification, scalable computing power and container orchestration via Amazon EC2 and Amazon EKS, and a security layer with Amazon GuardDuty, AWS Security Hub, and end-to-end encryption via AWS Key Management Service.

More features on the way

The immigration service plans to expand THIM later. Plans include online visa extensions, digital 90-day reporting for foreign residents, and eventually more automated border control for various nationalities.

For tourists, expats, and winter residents, this can make a big difference. Less paperwork means less stress upon arrival, especially after a long flight from Europe. At the same time, the question remains how smoothly the app works in practice, particularly for travelers who are less comfortable with digital systems.

With THIM, Thailand is taking a clear step towards digital border control. The promise is attractive: faster immigration, fewer repeat offenders, and better security. Whether travelers experience it that way will become clear once the app is used on a large scale.
