FAQ

Our Qualified Document Signing Service is designed to integrate with any information system. It enables you to turn your daily documents into qualified digital documents conforming eIDAS regulation.

What is an electronic signature?

According to the European Commission, an electronic signature is an electronic indication of a person’s intent to agree to the content of a document or a set of data to which the signature relates.

What are the different types of electronic signature?

The European Union’s (EU) 2014 eIDAS Regulation classifies electronic signatures into three levels: simple (SES), advanced (AES), and qualified (QES). Each level carries a different degree of security, trust, and legal strength. Of the three, only the Qualified Electronic Signature (QES) carries the same legal weight as a handwritten signature across the EU.

What makes Veriffy an expert in electronic signatures?

Veriffy is a Qualified Trust Service Provider, officially listed on the EU Trusted List. Our electronic signature solutions comply with the European eIDAS framework and support different signature levels according to business and regulatory requirements. Our expertise is built on 15 years of experience and confirmed by internationally recognized security and quality certifications.

What features does Veriffy's electronic signature API include?

With Veriffy API you can prepare digital documents for signing in multiple formats, customized to your unique needs and system design.

You can collect signatures remotely, share documents with others, and verify signer identities before signing.

Every document gets a complete audit trail and a qualified timestamp, automatically prepared for long-term archival storage.

The API integrates with other systems, is mobile compatible, and complies with industry standards and regulations to keep your documents legally binding.

How do I integrate Veriffy's electronic signature into my existing system?

You can integrate Veriffy into your existing systems in two ways: through our REST API, or by embedding our ready-made UI widgets directly into your application. Either way, you won’t need to overhaul your existing systems to add digital signing to your workflow. Our team of experts will guide you through the integration process and provide ongoing support to ensure a smooth transition.
