What is an electronic seal (e-seal)?

The concept of electronic seal is similar to the one of electronic signature. The difference is that the electronic seal is an evidence that a digital document was authorized by a legal entity, while the digital signature belongs to a natural person. Comarch Document Signer is a tool that allows to seal documents on behalf of your organization.

Strong authentication

A certificate issued by trusted third party and appended to the signature is a proof of who actually signed the document. Identity confirmation is displayed in a PDF reader when opening the file.

Data integrity

No changes can be made to a document after it has been signed.


The authenticity of the electronic seal is unquestionable – you’re protected against document forgery.

Use cases

Mass document signing (invoices, documents, agreements, etc.)

Authorization of internal and external documents

Contract signage

Authorization of documents submitted by customers

These days, the last use case is especially timely as governments provide financial aid for enterprises. To apply for financing, entrepreneurs need to submit an online application, authorized by a trusted entity. With Document Signer, financial institutions can act as trusted entities and authorize customer documentation.

When one of the banks asked us to sign applications related to the anti-crisis shield, the key criteria for the solution were the implementation time and reliability, which we’ve met in full. I am very glad that after just 7 days the solution started to serve the bank's customers.
