Digital signatures with qualified signatures

Digital signatures with qualified signatures

In the digital world, the qualified signature replaces the hand-written one. It helps companies and public authorities to digitize their business processes because electronic documents can be signed in a legally recognized manner, especially when processes are subject to the written form requirement.

Qualified certificates for electronic signatures in the form of a smartcard, i.e. signature card, are always issued to a natural person. The signature card cannot be transferred to another person. Recipients of an electronically signed document can be certain that the signature is in fact from the sender and that the contents of the document have not been manipulated.

Your advantages at a glance

Legally binding – Replaces the hand-written signature with the digital signature

Effective – Electronic business processes without any annoying changes to another medium

Secure – Authentication on the net based on high-security cryptographic keys

Certified – Warrants the highest level of data security through D-TRUST

FAQs

In the digital world, the qualified electronic signature (QES) replaces the hand-written one and can be used to electronically sign purchase agreements, orders and offer letters in a legally binding manner. The qualified signature card is always issued to a natural person and cannot be transferred to anyone else.

The electronic seal, on the other hand, ensures that the documents originated from a certain organization and are genuine. It is the digital counterpart to the company stamp or the public agency seal.

As required by law, the person ordering a signature card for digital signing must always be identified in person. This is the only way to ensure legal certainty. 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): More than 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

Please note: The 'electronic certificate of origin' signature application only works with the IHK signature card and not with the D-TRUST standard card. You cannot apply for multisign cards at the chambers of industry and commerce.
 

You need a signature card in order to create an electronic signature. You will also need a reader and – depending on the application you wish to use – additional software. Card readers can be purchased from Firma Reiner SCT.

Applications, such as MS Outlook, Lotus Notes or the ‘electronic certificate of origin’, can communicate directly with the reader and require Nexus Personal as additional software.

In order to electronically sign files (e.g. in Word, Adobe), you will have to use verified and certified signature software.
