In this post, we share our team’s digitally signed holiday card: a small experiment involving 18 people, 13 identity providers, and one signing queue. It’s a reminder of what eID Easy makes possible: secure, compliant, cross-border signing that simply works.

eID Easy Holiday Card Signed with 13 identity providers

As 2025 comes to a close, we want to extend our Season’s Greetings to our partners, customers, and friends around the world.

This year, our eID Easy team decided to celebrate the holiday season with a hands-on experiment that perfectly captures who we are: a globally distributed team passionate about digital signatures, trust services, and making electronic identity easy for everyone.

We created a digitally signed holiday card, completed by all 18 members of the eID Easy team. The PDF was signed with 13 different identity methods using our global API, exactly the kind of  workflow our customers run in production.

In the screenshot, you can see the final PDF opened in Adobe Acrobat, where all 18 signatures appear as valid. Adobe’s certificate panel on the right highlights each signer, the timestamps, and the full validation chain:

A Worldwide Mix of Signing Methods: All in One Document

Each teammate signed using their preferred national, regional, or worldwide eID solution. The final card includes signatures backed by 13 different providers:

  • Evrotrust
  • Estonian ID-Card
  • Smart-ID
  • Estonian Mobile ID
  • itsme
  • D-Trust
  • Austrian Handy-Signatur
  • ZealID
  • Trans Sped
  • InfoCert
  • Chave Móvel Digital
  • SimplySign
  • Latvian eParaksts Mobile

All connected seamlessly through the eID Easy API that coexisted smoothly within a single signing flow.

How We Signed the Card: The DSS Report

We prepared a single PDF and added all 18 team members to a signing queue. Over the course of a couple of hours, everyone signed the document from their preferred device and location, spread across multiple different time zones. Each signature was embedded as PAdES Baseline-LTA, which enables:

  • Full long-term validation support
  • Qualified timestamps
  • Certificate chain validation
  • Archived evidence for future verification

Once the last signature was complete, we downloaded the file and ran a full validation through DSS. Here are the results:

✔ 18 valid signatures out of 18

✔ All signatures passed qualification and integrity checks

✔ All timestamps passed verification

✔ The final PDF is fully suitable for long-term preservation

Qualification Levels

Most signatures were validated as Qualified Electronic Signatures (QES), with a few AdES/QC signatures backed by Qualified Certificates. All met EU Trusted List requirements.

Timestamps

Every signature includes one or more timestamps issued by the SK Timestamping Unit. The document accumulated a sequence of partial and full timestamps as signatures were added. All timestamps were marked PASSED.

Signing Time Observations

Across all 18 signatures, the average completion time was about 30 seconds. This offers a realistic snapshot of how smooth and fast mixed-identity signing can be in everyday workflows.

Wrapping Up the Year

This small internal experiment reminded us why we build eID Easy → To make digital identity interoperability simple, reliable, and accessible, whether a document has one signer, eighteen from all corners of Europe, or hundreds across the globe. 

Thank you for being part of our journey throughout 2025. We wish you a peaceful end of the year and many securely signed documents in 2026.

Warm greetings,

The eID Easy Team
