For the public sector
For government offices, universities and regulators. Officers, employers and citizens check permits, licences and certificates on the spot, and you keep full control of your data, even on your own servers.
Forged licences and certificates cost revenue, put people at risk, and leave officers guessing. Authstamp gives every document a check anyone can run.
Permits, licences, approvals and official letters.
Certificates, transcripts and letters of completion.
Registration certificates and practising licences.
Any document an officer, employer or citizen needs to rely on.
