Signature on one device

Modified on Tue, 11 Jun at 4:24 PM

Signing documents electronically makes sense even if the signatories are present in one place:


Even if you see each other, once you sign, you get a legally binding document in electronic form that you can hand over immediately.


For more information see:


Signature scenario assignment

This is done with the Signature on one device function. If you have this functionality enabled, you select it for each document individually, after uploading the document in the document header:



In the case of signing on one device:

  • all signatures take place on the proposer's device,

  • the email addresses of the signatories are entered only for the purpose of final transmission of the signed document,

  • notifications or prompts for signing are not sent,

  • each signer only enters a PIN to verify their identity via their phone..


Example of signing HR documents at the workplace

One of the typical situations of using a signature on a single device is signing HR documents.


This is a situation similar to the one where:

  1. The draft contract in paper form is first signed by the charter officer or director at the head office,
  2. The document is sent to the relevant facility.
  3. At the facility, a representative of the employer, e.g., the facility manager, and the incoming employee sign together, where the facility manager just hands over the document and the employee signs it.


How does that signature scenario look like set up in Signi:

  • "It depends on the order" is checked, i.e. as the signers are listed in the signature scenario, they will be asked to sign.

  • "Sign on one device" is checked i.e. the last two in the scenario sign together

  • The first to sign the set of documents is the Proposer Demo's statutory officer.

  • Employer's representative at the establishment Employee No.1 along with the incoming Employee No.2 sign together on one device.

  • The former only approves, i.e., his signature is not visible in the document. However, there is a record of the handling of the document in the audit trail in the Audit Trail.

  • The second signs, i.e. his signature will be visible in the document. At the same time, in the audit trail in the Control Sheet, there is a record of the handling of the document in signature mode on one device. So it will be evident that both have signed at the same time.


Example of a signature scenario: First, the documents are signed by the employer's statutory or authorised officer, typically at the head office, then another representative of the employer, after his/her approval, forwards them to the incoming employee at the premises for signature. The signature script is saved for reuse under the title "Employee Onboarding"


How signatories are identified when signing on one device

In the standard Signi signing process, each signer is authenticated via their email and phone - this is called two-factor authentication, 2FA.


In the case of single-device signing, the identity verification of the signatories is weaker. For counterparties, such as employees, the identity is verified only via phone - the counterparty signs on the claimant's computer, tablet or mobile phone, but a text message is sent to the counterparty's phone with a PIN that must be copied to the claimant's device.


Then, depending on the method of signing, what other information about the signatory's identity will be available to the controlling authority or law enforcement agency when using :

  • A biometric signature, a visual form or progression of the signature is available in Signi

  • BankID SIGN will provide the data from the bank, although the signature is called up on the claimant's device, the signer makes the confirmation on his bank's mobile app running on his mobile

  • for qualified signatures, sufficient data is provided by the certification authority that issued the certificate,

  • if the signature in the electronic document is officially authenticated, the related verification clause is available..


The choice of the signatory identification rate is always a trade-off between its availability, cost and conclusiveness. When weighing the risk of identity disputes, it is important to consider how often the dispute arises in a particular agenda, what the potential financial impact is compared to the benefits of getting rid of paper documents. It should also be remembered that even a handwritten signature on paper is not attributed by forensic experts to a person with 100% authenticity and this risk is commonly accepted.


How to make your job easier by saving a signature script

Tip: It is useful to save more complex signature scenarios for reuse, see 
Saved signing scenarios - Shorten your document submission to a few clicks. Then typically just change the signing counterparty.


Similar functionality with integrated Signi

Similar functionality can be provided in an application integrated with Signi. Directly in the application, clicking a button, selecting a currency or link will open the Signi page for signing by the respective signatories.
