The app is designed to modernise immigration services for Thailand, which receives roughly 30 million foreign visitors a year, with Bangkok ranked the world’s most-visited city by international arrivals in 2025, reports the Bangkok Post.
THIM is scheduled to launch on Oct 1, developed by Digital Identity and leveraging AWS cloud services.
The Immigration Bureau envisions THIM becoming a “super app’ for foreigners in Thailand, reducing paperwork for expats and long-stay workers while paving the way for automated airport channels for tourists.
“THIM positions Thailand at the forefront of Southeast Asia’s digital immigration transformation through a national mobile platform,” said Pol Maj Gen Pratya Prasarnsuk, deputy commissioner of the Immigration Bureau, at the AWS Summit Bangkok yesterday (May 28).
The bureau previously relied on manual blue slips and outsourced data entry. Last year it introduced the web-based Thailand Digital Arrival Card, which processed more than 10 million travellers.
However, frequent visitors complained they had to re-enter all 20 fields for every trip.
With THIM, travellers complete their full profile only once. On future visits, they need to update just a few details, such as the flight number and return date.
The bureau said the process can reduce arrival card completion time to about three minutes.
The app is available now for pilot downloads and uses an electronic know your customer (KYC) process to verify user information against passport details.
Travellers do not need to show a QR code at immigration counters, according to the bureau. Their data syncs directly with the bureau’s system, allowing officers to confirm the completed digital form when they scan a physical passport.
The app supports English, Russian, Japanese and Chinese, with plans to expand to 15 languages.
In the future, the bureau wants THIM to become a comprehensive digital platform for all foreigners living in Thailand, featuring appointment booking, electronic extension services, online pre-submission of documents, status change applications and issuance of transaction-related certification documents.
For expats, THIM can support mandatory 90-day reporting and official electronic document requests, reducing visits to provincial immigration offices. Long-term visa holders, including those under Board of Investment or diplomatic status, may be able to access automated airport channels through facial recognition technology that compares real-time mobile photos with identity data stored in passport chips.
"We plan to work with private companies to offer exclusive privileges, benefits and freebies to tourists," said Pol Maj Gen Pratya.
Natakorn Tanachaihirun, chief executive of Digital Identity, added that "the border is Thailand’s front door".
THIM’s architecture uses AWS services such as artificial intelligence-powered optical character recognition for passport document verification, e-KYC workflows, compute orchestration, security and compliance.
Vatsun Thirapatarapong, country manager of AWS Thailand, said governments across Southeast Asia increasingly view digital infrastructure as "a strategic enabler of national competitiveness and citizen trust".
A crucial factor for the public sector is keeping personally identifiable information within the country, Mr Vatsun said.
AWS utilises a "sovereignty by design" approach, ensuring all data remains in Thailand and is strictly managed and controlled under Thai jurisdiction, he added.
