Key takeaways
- Thailand Post has launched Prompt Pass, a verifiable credential wallet inside its Prompt Post app.
- The first credentials are Digital Transcripts issued with SBAC, usable instantly at SBAC Career Day 2026.
- It was built by three partners: TKC (national infrastructure), Transformational (institutional adoption), and ShareRing (the verifiable credential engine).
- Credentials are W3C verifiable, tamper-proof, and privacy-first, using Self-Sovereign Identity and Zero-Knowledge Proof.
- Next on the roadmap: a network of Thai universities in 2026, then financial services, hospitality, and public administration.
Thailand just took a real step out of the paper age. Thailand Post has gone live with Prompt Pass, a verifiable credential wallet inside its Prompt Post platform, and the first documents flowing through it are Digital Transcripts issued with Siam Business Administration Technological College (SBAC). Students can now receive their academic records as tamper-proof digital credentials and use them on the spot, including at SBAC Career Day 2026.
This is the first production deployment of the national trust infrastructure we announced in April, and it matters because it was never the work of one company. It was built by three partners pulling in the same direction: Turnkey Communication Services PCL (TKC), Transformational, and ShareRing. Each brought something the others could not, and the launch only happened because all three showed up.
Why this launch is different
Thailand has near-universal internet access, yet the documents that decide the big moments in life still move on paper. Proving where you live, confirming a qualification, applying for a loan: each one tends to mean photocopies, queues, and counters that close mid-afternoon. Paper is the weakest link in the trust chain. It is easy to forge and slow to verify, and once your data is on a printed page you lose control of it.
Prompt Pass attacks that problem directly. A Digital Transcript issued as a verifiable credential can be checked in seconds, cannot be quietly altered, and stays under the control of the person who owns it. The student decides what to share and with whom. An employer can confirm a record is genuine without calling the institution. The forged-document problem simply goes away. Thailand Post frames it well with its own tagline for the service: Document Less, Live More.
Three partners, three jobs
What made this work was a clean division of labour. None of the three partners was a junior contributor. Here is what each one carried.
TKC: the national infrastructure backbone
Turnkey Communication Services is one of Thailand’s full-service digital infrastructure providers, with deep roots in telecommunications, cybersecurity, and large-scale digital systems for government and enterprise. TKC’s role is to merge that existing national infrastructure with global technology standards so adoption can scale without forcing organisations to rip out the systems they already run. As TKC’s leadership put it, the aim is to build a national trust infrastructure that reduces cost and increases transparency while staying ready for international connectivity. Without an infrastructure partner of that weight and reach, a pilot like this never leaves the lab.
Transformational: turning policy into adoption
Transformational is the digital transformation partner that translates strategy into something organisations will actually use. Led by Ariya Banomyong, formerly Country Head of Google Thailand and Managing Director of LINE Thailand, the team specialises in digital document trust and verifiable credential solutions, and works directly with corporates and state-owned enterprises. Transformational owns the hardest part of any rollout: getting real institutions to issue, accept, and trust digital documents. The SBAC deployment, with two campuses issuing live Digital Transcripts to students, is exactly that work made visible. ShareRing holds a strategic equity stake in Transformational, and the two teams operate as genuine partners on the ground in Thailand.
ShareRing: the verifiable credential engine
ShareRing supplies the credential technology underneath the wallet. Our platform is W3C Verifiable Credential compliant, DIATF certified, and ISO 27001 accredited, and it is already deployed across multiple international markets. The architecture is privacy-first by design. Using Self-Sovereign Identity and Zero-Knowledge Proof, a person can prove what is true without exposing the underlying data, and nothing is accessed without their explicit consent. The blockchain layer records the issuance, verification, and revocation of each document, so trust is anchored in infrastructure rather than in a filing cabinet.
The point worth repeating is that no single one of these pieces is enough on its own. Infrastructure without adoption is a demo. Adoption without credential technology is paperwork with extra steps. Credential technology without a national backbone never reaches scale. Prompt Pass exists because all three came together.
What SBAC students get today
The first real users are students. Through Prompt Post, an SBAC student can receive and store an Academic Record or Digital Transcript in digital form, then present it instantly when applying for a job. At SBAC Career Day 2026, that meant graduates could share verified credentials with employers on the spot, with no paper, no waiting on the institution to confirm anything, and no risk of a forged transcript in the pile. SBAC, which positions itself as a centre of excellence in digital technology, becomes one of the first education institutions in Thailand to put verifiable credentials into students’ hands.
It is a small cohort today, but the pattern is the important part. A transcript is just the first credential. The same wallet is built to carry professional licences, government-issued certifications, company affidavits, and more.
Built to standards, built to last
Prompt Pass sits inside Thailand’s own digital identity direction, under the Ministry of Digital Economy and Society and aligned to the standards of the Electronic Transactions Development Agency (ETDA). Thailand Post operates the service under ISO/IEC 27001:2022, and the credential layer is W3C compliant and built for cross-border interoperability. That combination matters: a credential that works only inside one organisation is a dead end, while one built to open standards can travel across institutions, sectors, and eventually borders.
What comes next
This is the first deployment, not the last. The roadmap moves from Thailand Post into a network of Thai universities later in 2026, with active conversations underway across financial services, hospitality, and public administration. Each new issuer makes every wallet more useful, and that network effect is the whole point of building shared infrastructure rather than another isolated app.
For ShareRing, this is the model we want to repeat: strong local partners, open standards, and a privacy-first credential layer doing the quiet work underneath. For Thailand, it is a credible step toward a country where verified documents move at the speed of everything else. TKC, Transformational, and ShareRing built this together, and we are only getting started.
Prompt Pass and Prompt Post are services of Thailand Post. Digital Transcripts are issued in partnership with SBAC.
Frequently asked questions
What is Prompt Pass?
Prompt Pass is a verifiable credential wallet inside Thailand Post’s Prompt Post platform. It lets people receive, store, and share official documents as tamper-proof digital credentials from a single smartphone app.
What is a verifiable credential Digital Transcript?
It is an academic record issued as a cryptographically signed digital credential. It can be verified in seconds, cannot be altered, and stays under the control of the student, who chooses what to share and with whom.
Who built Prompt Pass?
Three partners built it together: TKC provided the national infrastructure backbone, Transformational drove institutional adoption with issuers like SBAC, and ShareRing supplied the verifiable credential technology.
Is my data private?
Yes. The system is privacy-first by design. Using Self-Sovereign Identity and Zero-Knowledge Proof, you can prove what is true without exposing the underlying data, and nothing is shared without your explicit consent.
What is next for Prompt Pass?
After Thailand Post and SBAC, the roadmap extends to a network of Thai universities in 2026, with active conversations across financial services, hospitality, and public administration.
