Credential flows designed for your sector

Whether you operate in finance, healthcare, education, or government — or are building with AI agents — TCS turns existing business processes into verifiable, selectively-disclosable, portable credentials.

One KYC, accepted across institutions

KYC, passport, and national-ID reference schemas

  • check_circle One KYC credential issued once, reused across banks, brokerages, and insurers
  • check_circle Selective disclosure shares only required fields — e.g. nationality and DOB — without revealing the full document
  • check_circle Verifiers cryptographically confirm the KYC provider's identity via the TCS Trust Registry
Aligns with: Taiwan PDPA (個資法) data-minimization; can be the technical layer beneath a 金管會 KYC-reuse pilot.

Professional licensing, vaccination records, and insurance claims

Medical-license, vaccination, insurance-claim reference schemas

  • check_circle Physician license credentials issued once; cross-institution verification is instant — no paper validation
  • check_circle Patients control portable vaccination and health-check credentials and choose which fields to share
  • check_circle Claim documents issued as credentials simplify verification across insurers and reinsurers
Aligns with: Taiwan PDPA (個資法) medical-data protections; deployable alongside 衛福部 / NHIA and commercial-insurance industry data-exchange rules.

Citizen identity, driver licenses, and professional licenses

Identity-card, driver-license, professional-license reference schemas

  • check_circle Agencies join the Trust Registry as issuers and publish identity, driver, and professional license credentials
  • check_circle Other agencies verify credentials against published rules — no point-to-point API integrations needed
  • check_circle X.509 (ES256) signing paths let trust chains build on existing PKI and government CA hierarchies
Aligns with: 數位部 (Ministry of Digital Affairs) digital-wallet reference architecture (OID4VCI / OID4VP / SD-JWT VC); Taiwan PDPA (個資法).

school

Degrees and transcripts, verified in seconds

Degree, transcript, student-ID, and course-completion reference schemas

  • check_circle Degrees, transcripts, and student-ID credentials — employers verify directly without contacting the registrar
  • check_circle Graduates keep credentials portably and share them without involving the registrar
  • check_circle Individual courses and micro-credentials can be issued separately for lifelong-learning records
Aligns with: Taiwan PDPA (個資法); integrates with 教育部 (Ministry of Education) digital-learning attestation and inter-university credit-recognition flows.

Verified identity for the agentic web

Custom schemas model the delegating organization and scope of authority

  • check_circle AI agents present verifiable credentials to prove which organization they act for and under what authority
  • check_circle Headless verification: an agent verifies credentials with two API calls — no wallet UI in the loop
  • check_circle The Trust Registry cryptographically confirms the issuing authority, giving agents an auditable basis for trust decisions
Built on open standards: OID4VP 1.0 / SD-JWT VC headless verification; delegation credentials follow the standard custom-schema registration path.
