Digitempli teenuse piltFrom 01.07.2016 since the eIDAS regulation took effect, SK is included in the Trust List as a service provider for issuing qualified certificates for e-Seal.

e-Seal is used for certifying digital documents. It proves that electronically sent documents or other information originates from the institution that sent them. e-Seal ensures that the respective institution is associated with the specific document and the document has not been altered in the meantime.

e-Seal can be used with digital signature, as well as without it. Using the certificate for e-Seal along with the person’s digital signature you can be sure that the person who signed the document is authorised to sign documents on behalf of the respective enterprise.

Business advantages

e-Seal can be used by legal persons acting both in the public or private interests.

e-Seal saves your time and costs, because instead of manual administration of former paper documents you can certify and send documents digitally. e-Seal ensures the authenticity of documents and customers can carry out necessary operations more quickly and conveniently.

The use of e-Seal is like the use of ID-card while signing, i.e. the time of giving the stamp and the validity information is added to the document. e-Seal can be used with eID software. e-Seal solution can be integrated into most information systems.

e-Seal can be used in several business sectors. For example, banks issue payment order confirmations certified with e-Seal to prove the execution of payments. e-Seal is also used in real estate appraisal reports, in digital letters of trust sent to the Estonian Motor Vehicle Registration Centre by leasing companies and in certificates issued by the National Examination and Qualifications Centre.

The advantage of the qualified e-Seal on qualified certificate is that the stamp issued in one EU member state is recognised by all the member states.
