The Certification Body ESS QCA, upon issuance of a qualified certificate for electronic seal, suspends it. The suspension after issuing the certificate is a protection measure against the compromise of the QSCD device during transport to the user.
The user via the online service, on the Activation link, activates the certificate using two parameters:
• a one-time activation code (JAK) that was sent directly to the user via SMS and
• unique user identifier (UIK) printed on the QSCD device that was handed over.
The PIN change procedure can be performed through the QCA QSCD Manager application by following the simple instructions on the application itself. You need to have your QSCD device with a qualified certificate with you – smart card (and appropriate reader) or token, as well as the PIN code you received in the PIN envelope. An explanation of this procedure can be found in the document Instructions for using a qualified certificate for electronic seal.

In case of entering the wrong PUK in the PIN unblocking process two (2) times, independent PIN unblocking is no longer possible. In this case, device unlocking can only be performed by the ESS QCA Certification authority. The use of other application solutions for change/unblocking is not recommended, as the QSCD device can be permanently destroyed in this way.
The user can apply for unblocking the device for a qualified certificate for electronic seal. The application must be submitted in the RA body. When submitting a request for unblocking, it is necessary to enclose a blocked device, as well as an authorization to manage a qualified certificate for electronic seal (which contains the name, surname and identity card number of the person who brings the QSCD device, as well as the signature of the legal representative of the subscriber). After the identification of the authorized person, the device is unblocked and then the PIN envelope is printed, which is handed over to the authorized person along with the unblocked device.
