Ministry of Digitization has made available A new service in the mCitizen application: free qualified signature. Every adult person with an mCitizen in the application and a valid e-card (NFC) can sign up to 5 documents per month for free. This solution is dedicated exclusively to private matters, not related to professional activities.
"Civil" examples where a private signature makes sense:
In short: if you sign as yourself - privately, and not "on behalf of the company" - mCitizen is completely sufficient. If you are acting on behalf of a company, then you need a qualified commercial signature - SimplySign or Certum Mini.
A business, company or foundation has different needs: larger scale documents, professional attributes in the certificate, integrations with systems, and No limitation to 5 signatures/month. This is where commercial qualified signatures, e.g. SimplySign (mobile) or Certum Mini (card/USB), which you can buy and handle through podpisano.pl.
Qualified signature typical business applications (examples):
The official Ministry announcement makes it clear: the free signature in mCitizen is "for handling private matters".. So if the document relates to professional activity (your JDG, company, employer's representation), choose a commercial QES - so you have full freedom of use, no limit, and it is easier to demonstrate the correct context (role in the organization).
No. The service is addressed to private matters - That's according to the MC's official information. In practice, this means that documents related to business activities sign with a commercial qualified signature (such as SimplySign or Certum Mini). It's also the safest evidentiary route when you're signing "on behalf of" a company and need consistent attributes and a history of unlimited use.
Here's a comparison of the major differences - especially file formats and "capacities."
