Thailand Post puts verifiable credentials in a national app

The problem was paper

Thailand has near-universal internet access, and 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.

What was built

Prompt Pass is a verifiable credential wallet inside Thailand Post’s existing Prompt Post platform. 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. Thailand Post’s own tagline for the service is Document Less, Live More.

Three partners, three jobs

None of the three was a junior contributor, and the launch happened because all three showed up.

TKC

Turnkey Communication Services PCL is one of Thailand’s full-service digital infrastructure providers, with roots in telecommunications, cybersecurity and large-scale digital systems for government and enterprise. Its job was merging that national infrastructure with global technology standards, so adoption can scale without organisations ripping out the systems they already run.

Transformational

The digital transformation partner that turns 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 works directly with corporates and state-owned enterprises. It owned the hardest part of any rollout: getting real institutions to issue, accept and trust digital documents. ShareRing holds a strategic equity stake in Transformational.

ShareRing

The credential technology underneath the wallet. Self-Sovereign Identity and Zero-Knowledge Proof let a person 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.

What a student gets

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: no paper, no waiting on the institution to confirm anything, and no risk of a forged transcript in the pile.

It is a small cohort today, and the pattern is the important part. A transcript is only the first credential; the same wallet is built to carry professional licences, government-issued certifications and company affidavits.

Built to standards

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 is the point. A credential that works only inside one organisation is a dead end. 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 conversations underway across financial services, hospitality and public administration.

Each new issuer makes every wallet more useful, and that network effect is the reason for building shared infrastructure rather than another isolated app.
