Your qualified e-signature, issued after one video call.
SimplySign is Certum's cloud-based qualified electronic signature. You confirm who you are on a video call with IDnow, holding your passport, and then sign from your phone or computer. No card, no reader, no trip to Poland.
Same legal effect as a handwritten signature in every EU member state (eIDAS, Art. 25).
What you get
- A qualified electronic signature (QES)
- The highest level of e-signature defined by EU regulation 910/2014 (eIDAS). Courts, registries and counterparties in all 27 member states must treat it like your handwritten signature.
- Nothing to plug in
- Your signing key lives in Certum's certified cloud device. You unlock it with the SimplySign app on your phone, so there is no smart card or USB reader to carry around.
- Recognised by PDF software
- Adobe Acrobat and Reader recognise Certum's qualified certificates as trusted, so your recipient sees a valid signature when they open the signed PDF.
- One, two or three years
- Pick the certificate validity that fits your plans. Before it expires we remind you and help you renew it.

Video call with IDnow
An IDnow agent asks you to show your passport or national ID card to the camera, tilt it so its security features are visible, and look into the lens.
-
Activate and sign
Install the SimplySign app, set your PIN and activate the certificate. From then on you can sign PDF and other documents whenever you need to.
Have these ready before the call
- A valid passport, or a national identity card from an EU or EEA country
- A smartphone with a working camera and a stable internet connection
- Your own e-mail address and mobile phone number, not shared with anyone
- A quiet, well-lit room where you can be alone for the length of the call

Questions
Do I need to live in Poland or the EU?
No. Remote verification is available to citizens of many countries with a valid passport. We check your document type before you pay, so you won't be charged if it can't be verified.
Is the signature valid outside the EU?
Inside the EU it has the legal effect of a handwritten signature by law. Elsewhere, including the United States, it is a strong, verifiable electronic signature, but how it's treated depends on local rules and on the party receiving the document.
What does it cost?
The price depends on the certificate validity and includes the video verification. We send you the full total before you pay anything, and nothing is charged without your confirmation.
How long does the video call take?
Plan for about fifteen minutes, including a short wait. The agent guides you through each step, so you don't need to prepare anything beyond the items listed above.
Who sees my passport?
The video call is run by IDnow on behalf of Certum (Asseco Data Systems), the qualified trust service provider that issues your certificate. We receive only the details you type into the form on this page.
Can I get an electronic seal for my company instead?
Yes, but it follows a different process because it is issued to the company, not to you. Mention it in the form and we'll send you the options.
