ECSigner mobile qualified digital signature
The ECSigner mobile qualified digital signature is a modern solution compliant with the eIDAS Regulation, which has the same legal validity as a handwritten signature throughout the European Union.
By choosing ECSigner, you receive a comprehensive service including a qualified certificate, mobile and desktop applications, access to the management portal, and full technical support throughout the certificate’s validity period.
The entire process of issuing the signature takes around 20 minutes, and activation takes place immediately after verification is complete.
We tailor the identity verification method to your needs. You can opt for online verification, without leaving your home, or choose in-person verification at one of our partner locations across Poland.
In both cases, the process is quick, secure and carried out by qualified specialists.
ECSigner offers maximum ease of use. All you need to sign documents is a computer and a smartphone.
Thanks to two-factor authentication (2FA) and one-time OTP codes, your data remains properly secured, and if you change or lose your phone, you can easily activate the service on a new device at no extra cost.
ECSigner’s cloud-based qualified digital signature works with popular software and systems used by businesses, public administration and financial institutions.
ECSigner enables you to sign private and business documents, handle official matters and conclude contracts remotely – quickly, securely and entirely electronically.
Identity Verification at a EuroCert Stationary Point
Identity verification at a physical location is a secure and proven process for confirming a customer’s personal information through an in–person visit to an authorized location.
This solution is particularly valued by companies and institutions that require a high level of reliability—for example, when signing electronic documents, entering into contracts, or issuing certificates.
EuroCert Qualified Certificate
The EuroCert Qualified Certificate enables you to sign PDF and XML files with a qualified digital signature. The PAdES format is used for PDF documents, and XAdES for XML files. This allows you to sign contracts, invoices, declarations and other electronic documents without having to print them out.
