WHERE IT FITS

Credential flows designed for your sector

Whether you operate in finance, healthcare, education, or government, 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 A KYC provider issues an identity-verification credential once; the customer reuses it across banks, brokerages, and insurers
  • check_circle Selective disclosure lets the customer share only the minimum required fields (e.g. nationality + DOB) without revealing the full document number
  • check_circle Verifiers cryptographically check the original 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 Medical institutions issue physician license credentials — cross-institution and regulator verification happens instantly (no paper validation step)
  • check_circle Patients control portable vaccination and health-check credentials and choose which fields to share with a new provider or insurer
  • check_circle Insurance claim documents can be issued as credentials, simplifying 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 card, driver license, and professional license credentials
  • check_circle Other agencies (including cross-ministry and cross-municipality) verify these credentials against the published rules — no point-to-point API integrations needed
  • check_circle Supports the X.509 (ES256) signing path, so trust chains can build on existing PKI / 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 Universities issue degree, transcript, and student-ID credentials — employers and other institutions verify directly without phoning the registrar
  • check_circle Graduates keep their credentials portably — verifiable across employers and other institutions without contacting the registrar each time
  • check_circle Individual courses or micro-credentials can be issued separately to support 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.
