You have received a new signature card. Before you can use it to create a signature, it must be initialized, i.e. activated.
Depending on the trust center, individual PINs can or must be assigned during this process.

Depending on the trust center, you will receive information about which software you can use to initialize your card together with the signature card – or with a separate PIN letter.

Please note:

After initialization, a confirmation of receipt must be sent to the trust center. This usually happens online. Only then will the certificate of your signature card be included in the directory service and a signature created with this signature card can be validated.
