Choose the right certificate for your use
Professional certificates
With a professional certificate you sign as a recognized practitioner. In addition to your identity it confirms your professional title or authority, for example as a notary, lawyer, accountant, or doctor, so the recipient knows you are authorized to act in that capacity.
Association certificates
With an association certificate you sign visibly as a member of your trade or professional association, for example as an estate agent. Clients and principals can immediately see you are affiliated and meet the association's standards.
Company certificates
With a company certificate you sign on behalf of your organization, with the company name in the certificate. This combines the legal validity of a qualified signature with clear professional recognizability.
