FAQs – Frequent questions regarding our D-TRUST signature and seal cards

We have compiled the answers to frequently asked questions here for you.

Card orders

As required by law, the person ordering a signature and seal card must always be identified in person. This requirement is laid down in the eIDAS Regulation for qualified trust services. This means that the applicant must present an ID card or passport that is valid for at least another four weeks.

When submitting an application, you have the following options:

  • PostIdent method: You fill out your application documents and go to a post office to have your identity confirmed using the PostIdent method.
  • IHK (Chamber of Industry and Commerce): Over 60 chambers of industry and commerce  throughout Germany offer a signature service. They will guide you through the application procedure and you will be identified at the same time. An overview can be found here.
  • D-TRUST registration partner
  • D-TRUST on site in Berlin: You can contact us by sending an e-mail to: service [at] d-trust.net.

If you have a D‑TRUST card and have therefore already identified yourself, you can apply for a follow-up card, a replacement card or a second card without having to identify yourself again in person. This simplified application method is open to you if:

  1. your name has not changed in the meantime or
  2. no more than 180 days have passed since your old signature card expired.

You can apply for a follow-up card here.

Follow-up cards are not available for seal cards.

SMS/TAN method

If you have not yet requested a signature or seal card, you can enter your mobile phone number in the first-time request. We will store the number exclusively for this purpose so that it can be used for the SMS/TAN method.

If you already have an activated signature or seal card, you can register your mobile number later. To do this, you will need the registration secret that we already sent to your registered address by post. You can apply for your registration secret here.

By providing a mobile phone number for a new or existing signature or seal card, we can offer you the following options:

  • Electronic activation
    Up to now, our process was designed so that you confirmed receipt of the signature or seal card and PIN letter by signing the confirmation of receipt. You then had to send back the original confirmation of receipt to us.

This procedure is still possible, but if you have provided us with a mobile phone number you can also confirm receipt using a TAN. This speeds up the activation process significantly because neither the confirmation of receipt has to be returned nor the manual check carried out.     

  • Electronic blocking: Link to the revocation portal
  • Online application for a follow-up card (instead of the order Password)
    In addition to requesting an order password in order to apply for a follow-up card online, we can offer you the SMS/TAN method. After requesting the order password, we will generate it and send it to you by post. The SMS/TAN method is a digital alternative where the postal procedure is no longer needed. This is a faster option for applying for a follow-up card.
  • Electronic complaint regarding a card/replacement card
    Up to now, any complaint regarding a signature card meant that you had to complete the application again and provide your data. This application and the card were then sent to us. With the SMS/TAN method, your application data is displayed to you so that you do not have to enter your data again. Replacement cards are applied for in the same way.

Card initialisation and installation

For security reasons, you can only activate your signature card by entering the correct transport PIN. We will provide you with your PIN codes for your certificates in a PIN letter that is sent separately from the card. Please observe the brief instructions for this:

  • Initialisation of your D‑TRUST Card
  • Initialisation of your D‑TRUST Seal Card

In order for third parties to be able to verify your certificates, they must first be published in our repository service. This means that you must first confirm that you have received the card and the PIN letter. You can do this using our SMS/TAN method or you can sign the attached confirmation of receipt and return this to D‑TRUST.

Only then will your card be activated in the repository service so that you can generate valid signatures.

Revocation of signature cards

If you have lost your signature or seal card or if it has fallen into the wrong hands, you are obliged to immediately revoke your certificates. Information concerning revocation can be found here.

Pursuant to the eIDAS Regulation, a trust service provider (D‑TRUST) must immediately revoke a qualified certificate if:

  • This is demanded either by a signature key holder or their representative (third party authorised to revoke).
  • The certificate was issued on the basis of incorrect data.
  • The trust service provider discontinues its activities and if such activities are not continued by another trust service provider.
  • The certificate holder (you) fails to fulfil their contractual obligations.
  • Other reasons for revocation were considered in appropriate agreements.

As soon as you no longer need your signature card, you can have it revoked or you can destroy it yourself, for instance, using a punch in order to destroy the chip. Please remember that you will need precisely this card and the pertinent keys and PINS to decrypt any data which was encrypted using this card. Therefore, if you still need the card to decrypt data, you should keep it in a safe and secure place.

General questions

In order to use the signature card, you will need a card reader and, depending on the application which you wish to use, additional software. You can purchase suitable card readers, middleware or signature software from Reiner SCT.

Certain applications, such as Microsoft Outlook, Lotus Notes or Firefox, are unable to communicate directly with the reader and require Nexus Personal as middleware.

Unlike the standard signature card, the multi-sign card can be used to perform several signing processes by entering the PIN just once.

D‑TRUST’s Multicard is used in secure environments, for instance, in a server room. If you need a multi-sign card for your office, please use D‑TRUST’s Multicard 100.

In all cases, special licensed signature software is required to use a multi-sign card.

Unlike a signature card, the certificates of a seal card are issued for a legal entity (e.g. public authority or organization). Since no natural person is named in the certificate, a seal card can also be used by all authorised employees.  Seal cards are always used in order to sign purely for the organization (e.g. letters of reference, etc.).

Here you will find a list of signature software from various manufacturers that you can use with your D-TRUST signature card.

You can have a pseudonym in your certificate. This will then appear in the certificate instead of your name. This is indicated by the attachment ‘:PN’.

A fee is charged for each pseudonym which can be assigned just once. If the pseudonym selected already exists, we will have to reject or number your selected pseudonym. A desired pseudonym that, for instance, refers to the company name or describes the purpose of the signature card, can be entered in the application in conjunction with a D-TRUST Multicard.

It makes sense to enter a pseudonym when using multi-sign cards for electronic invoice management. A pseudonym for single-signature cards only makes sense in certain cases. Note: Many eGovernment applications cannot be used if the certificate contains a pseudonym. Pseudonyms are not used on seal cards.

A signature card that has been issued to a natural person may only be used by this person. That's because this would mean that you are giving your colleagues an unconditional blank signature which they can use to make legally binding representations in your name. Such representations are always deemed to be given by the owner of the certificate, no matter who actually used the signature card.

Note: A D‑TRUST seal card that has been issued to a legal entity can be used by several authorised individuals.

Additional products for your signature card, such as card readers, can be purchased from Reiner SCT.

Did you send us all the required documents by post? We cannot begin to produce your card until we have received everything. The production of your signature card involves several processes: from checking that the application documents are complete right through to issuing the certificate. Therefore, you can expect delivery of your signature card one to three weeks after submitting your application.

If this is your first application for a signature card, you can query the processing status of your card online at D-TRUST GmbH. Got to the Status reques and enter your individual application ID which is shown on the top right of the application form.

For security reasons, your PIN letter will be sent a few days after the signature card is sent.

You will receive an e-mail from us in time stating that your signature card is due to expire. You can apply for a follow-up card one month before and up to one month after your signature card expires. The follow-up application process for this has been simplified and is carried out on the basis of the application documents which D‑TRUST GmbH already has. You can once again find out more about the follow-up application process here.
