Thailand's previous online arrival system, TDAC, required international visitors to manually re-enter their personal and travel details on every single trip, for a country that receives roughly 30 to 33 million international arrivals a year.
In May 2026 the Immigration Bureau, working with the Thai company Digital Identity Co. on Amazon Web Services infrastructure (EC2, EKS, GuardDuty, Security Hub and AWS Key Management Service), launched THIM, the Thailand Immigration Management System. THIM uses AI-powered optical character recognition to read all three data layers of a passport — the machine-readable zone, the biographical page and, where present, the embedded chip — so that first-time registration takes under three minutes and repeat registration for returning visitors takes one to two minutes. The system was announced on 27–28 May 2026 at the AWS Summit in Bangkok by Immigration Bureau deputy commissioner Pol Maj Gen Pratya Prasarnsuk, AWS Thailand country manager Vatsun Thirapatarapong and Digital Identity CEO Natakorn Tanachaihirun; it launched supporting English, Russian, Japanese and Chinese, with a target of 15 languages by the end of 2026.
The processing-time figures come from the agency's and vendor's own launch announcements rather than an independent audit, and THIM was explicitly described as being in a pilot phase at launch, with planned features such as appointment booking and e-extension services not yet live. No third-party evaluation of the system's accuracy, security or fraud-detection performance had been published as of the announcement.
