To use the mSzafir application you must have a valid mSzafir certificate with a long validity period. You can buy it here on https://mszafir.pl. An mSzafir qualified electronic signature is provided by KIR - an entity entered, on the basis of a decision of the Ministry of Digitalisation, to the European register of trusted entities. The mSzafir mobile application is a convenient way to sign documents with a qualified electronic signature from your phone. Using the application, you can sign all documents in PDF format, anytime and anywhere. The mobile signature made in the mSzafir application is just as legally binding as a handwritten signature. The application also allows to generate the codes necessary to log into the mSzafir portal and sign documents via a browser. After logging into the mSzafir portal, you can view the available certificates, check the limit of signature for each of them, cancel the certificate or view your active mobile applications.
