FAQ about
the electronic signature inSign


What is inSign?

inSign logo
inSign is a software for electronic signatures that is developed and hosted in Germany. Any PDF document can be signed legally and digitally using inSign. The signature solution has already been on the market since 2013 and is market leader in the German insurance sector.

Which kind of electronic signature is inSign?

As a rule, inSign is used to gather so-called advanced electronic signatures (AES) in line with eIDAS. However, inSign also supports other signature types. In the case of qualified electronic signatures (QES), a corresponding trust service is incorporated into the service.

More information on the three signature types

How is an electronic signature created using inSign?

How is an electronic signature created using inSign? The document is uploaded to inSign or alternatively, can be transferred via API. Signature fields, check boxes and text fields can then be added afterwards. The document is then either signed immediately and/or other signatures can be requested. The signature can be made without any special hardware – such as an MDE device – using any current browser. A touch-sensitive device such as a smartphone or tablet is required for the handwritten signature. No touch device is required to enter the name using a keyboard or the certificate-based signature. All processes are clearly displayed in the process management section. Documents can be opened, downloaded or deleted.

Can a document be signed directly on the computer?

It is possible to sign a document in the browser directly. In the case of a handwritten signature (AES), a touch-sensitive screen is required for signing. If the computer does not have a touchscreen, the signature request can be redirected to a smartphone or tablet. inSign has its own automatic screen-type recognition function, and shows the user which options they have for redirecting the signature.

Is there an app?

Yes, the app is an optional extension to the online application for users who sign on a regular basis. The e-signature is usually made directly in the browser (Chrome, Safari, Edge, Firefox, etc.).

Where can I find the login code for the inSign app?

The inSign app can only be used in combination with a licence. The login code to connect the app with the online application can be found in the online application.

Do I have to download inSign 365?

No, inSign 365 is a cloud-based online application. You can find it under the following link: https://app.getinsign.de/.

Which features does the e-signature solution offer?

Depending on the type of licence, the software has the following features:

How does the weblink feature work and what should be taken into account?

inSign customers can have the system generate a weblink (Internet URL) for a template. This link can be embedded into one’s own website. Whenever visitors to the website click this link, inSign automatically creates a process from the template and opens this process for the website visitor. They can fill out and sign the document, close the process and download the document copy. The inSign customer will then automatically receive a notification and can download the completed document via the process management section.

How is a process forwarded to another person/other people?

A link for signing the process is sent e.g. via email to one or more person(s). The link to the document and the login password are sent separately. Two-factor authentication is possible, among other things.

Can a document be signed by multiple persons?

Yes, a process can be signed by multiple persons, by creating multiple signature fields. These can be allocated to the signatory. It is also possible to determine the order of the signatures.

Can processes also be declined?

Yes, processes can also be declined by the signatory with good reason.

What are the technical requirements to be able to use inSign?

All that is required for inSign is an up-to-date browser. In the case of a handwritten signature method, a touch-sensitive screen is required for signing by hand. If the computer does not have a touchscreen, the signature request can be redirected to a smartphone or tablet.

Why is the digital signature the better alternative to the scanned / faxed signature?

Scanned and faxed signatures are hardly provable because it is only an image of the signature. The identity is difficult to prove. Digital signatures are linked to data that can be assigned to a person.

What sets inSign apart from its competitors?

  • High data protection requirements
  • High market acceptance
  • Different types of signature possible in one document
  • Confidentiality in line with section 203 of the German Penal Code (StGB)
  • Specifying the position of the optical signature in the document
  • Form editor and special features
  • Document protection following the signature
  • And much more …

biometric features by example
Play Video about biometric features by example
Yes, depending on the type of signature, a wide range of data can be used as proof in the case of dispute, including
  • Audit logs
  • Email addresses
  • Biometric signature files (AES)
  • Qualified certificates (QES)
In the case of a handwritten electronic signature, the writing process (the handwriting style) is recorded during signing. The biometric data captured in this way are encrypted and embedded in the PDF document.

The identity of the signatory is determined in advance with the qualified electronic signature. An evidence-safe document is created when signing takes places with a two-factor authentication.

Is inSign compliant with GDPR and eIDAS?

The digital signing process takes all legal requirements into account, without exception. This includes the GDPR and eIDAS, as well as BGB and BDSG. See also: www.getinsign.com/legal-data-protection/

The Swiss federal law on electronic signatures ZertES is equivalent to the European eIDAS regulation. inSign is in accordance with both eIDAS and ZertES. For the qualified electronic signature, we work together with approved trust services.

What happens if the paper signature and e-signature do not match?

It is not unusual for there to be differences between the paper and screen signature. However, in the case of the handwritten signature with inSign, other data are captured alongside the image of the signature, for example, the speed and direction of the writing. These characteristics are different for every person. This makes it possible to prove the authenticity of a signature, even in the case of visual deviations.

How do I know if a document has been altered?

As part of the electronic signature, inSign has applied a digital certificate with a checksum to the document. This certificate/checksum can be validated. Various online services or software programmes are available for this purpose. Many users like to open the document in Adobe Acrobat Reader, as validation is carried out directly.

Should the document have been subsequently altered, this will be labelled with a red x and with the following annotation: ‘This signature is invalid. The documents were altered or damaged after the signature was added.’ If the symbol is green, everything is okay.
Signature valid
Signature invalid

Why is inSign not listed among the trust service providers?

inSign is the software provider of the inSign signature solution and co-operates with well-known trust service providers such as D-Trust, A-Trust and Swisscom. Trust service providers are required exclusively for qualified electronic signatures. They check and validate the certificate-based signature.

Yes, the handwritten advanced electronic signature (AES) can be written with the finger as well as a pen using inSign. Other options for signing include entering the name or the certificate-based (QES) with the keyboard.

Other industry-independent application options

Is it possible to sign a document electronically using different signature service providers?

Technologically speaking, there is no reason PDFs cannot be signed using different digital signatures, but it goes without saying that compatibility between different signature service providers cannot be guaranteed. As a principle, we recommend using optional signature fields for this purpose.

Is inSign suitable for the insurance industry?

Yes, we have a number of reputable clients in the insurance industry such as Generali Versicherung and Nürnberger Versicherungsgruppe and have been market leaders in this sector for many years. The e-signature solution makes it possible, for example, to sign insurance contracts, consultation protocols, broker agreements, offers, etc. electronically. What’s more, we have developed an Insurance Contract Act (VVG) mode for the insurance industry, which ensures that the client has already received and read the respective document before the signature is made.

Licence and costs

Who needs an inSign licence?

Every person who provides documents for signing requires an inSign licence.

In the case of inSign 365, this is a user licence. This means that every licence is allocated to one person and may not be used by multiple persons. It is permitted to use different devices.

inSign enterprise can be integrated. This means that the licence is valid for all of the company’s business processes.

Does the signatory also need a licence?

No, neither a licence nor registration is required for providing a signature. Once the document has been approved, the signatory receives a processing link (and also a password, on request) which can be used to read and sign the document. The signatory will not be asked to agree with the general terms and conditions of inSign.
