What is Tvarka Sign?

For European businesses that need electronic signatures without paying for every employee, Tvarka Sign combines document signing, invitations, status tracking and signature verification. Legal and accounting teams can work with PDF, ADOC and ASiC-E files. Developers can connect their own applications through the signing API. Qualified signatures use supported identity methods, including Smart-ID, Mobile-ID and compatible Lithuanian identity cards. The service has no subscription or per-user fee. High-volume pricing at 1,000+ signatures/month is EUR 0.06 plus VAT for Lithuanian eID/USB and EUR 0.16 plus VAT for Smart-ID, Mobile-ID or LT ID. The 1-99/month remote-signing tier is EUR 0.19 plus VAT. Failed or cancelled signing is not billed. Access is available through a browser, Windows, macOS (beta), Android and iPhone. Official desktop and card-middleware downloads remain on tvarka.pro. A separate free Android offer covers personal, non-business use: ten PDF signatures per calendar month with an NFC phone and a compatible Lithuanian eID issued after 2024-01-01. Socialiniai algoritmai, UAB operates Tvarka Sign from Lithuania.

What is Qausal?

Qausal is an electronic signature service hosted in the cloud, enabling users to create and authenticate signed PDF documents efficiently. The platform allows individuals to upload PDFs, invite numerous signers, assign specific roles for signing, and track the signing process, all while permitting signers to participate without needing to register for an account. Utilizing the ML-DSA-65 post-quantum digital signature algorithm, which is acknowledged as FIPS 204, Qausal ensures that signatures remain valid even amid future advancements in quantum computing. Each signed PDF contains signature data, public keys, and hashes, and users can also request a proof bundle for verification using open-source tools. Additionally, Qausal supports the integration of quantum-safe attestation for documents signed on other platforms, maintaining the integrity of the original document. This solution is especially advantageous for businesses that need trustworthy verification of contracts and records, including those operating in the legal, financial, healthcare, and governmental fields. By offering these capabilities, Qausal helps users streamline their document workflows while safeguarding their agreements against the challenges posed by advancing technology, ultimately promoting confidence in digital transactions.
