Qualified Electronic Signature Application
A qualified electronic signature carries the exact same legal weight as a handwritten signature. It allows you to securely manage official matters, sign business contracts, and handle personal documents entirely from home.
📋What to prepare before choosing a signature
- Define signature scope: Determine whether you will use it for official administration (ZUS, KRS, ePUAP), business contracts, or personal documents.
- Check required file formats: Verify which formats your partner institutions require (PDF/PAdES or XML/XAdES).
- Verify potential limits: Check for transaction amount or technical limits imposed by individual providers.
