Signing documents and contracts still relies on fragmented processes in many organizations: handwritten signatures on paper, scans, email exchanges, manual archiving. Even when electronic signature tools are adopted, adequate guarantees on signer identity and document integrity after signing are often missing.

The result: contestable documents, slow processes, and compliance risks. Without a structured register of who signed, when, where, and how, proving signature validity in disputes becomes complex.

FAQ: digital signing of documents and contracts

1) How does the TrueScreen digital signing process work for documents and contracts?
The operator uploads the document to the TrueScreen platform and sends it to the signer via a dedicated link. The signer verifies their identity through OTP via SMS or video biometric verification, then applies their digital signature. TrueScreen automatically adds a qualified timestamp and records contextual metadata, sealing the document with a digital signature that guarantees its integrity and immutability.
2) What is the difference between TrueScreen digital signature and a simple electronic signature?
A simple electronic signature provides no guarantees regarding the signer’s identity and is subject to the court’s discretionary evaluation. The TrueScreen digital signature authenticates the signer through OTP or biometric verification, applies a qualified timestamp compliant with the eIDAS Regulation, and produces a tamper-proof document with full evidentiary value that is resistant to repudiation.
3) Is the TrueScreen digital signature compliant with the eIDAS Regulation?
Yes. The TrueScreen digital signature is compliant with the eIDAS Regulation for electronic signatures and qualified timestamps, with ISO/IEC 27001 standards for information security management, and with the GDPR for the processing of biometric data used during signer authentication.
4) How is the signer’s identity verified during the signing process?
TrueScreen offers two authentication methods: OTP via SMS, which sends a one-time code to the signer’s phone number, and video biometric verification, which requires brief facial recognition. Both methods ensure the signature can be attributed to a specific individual, making the signing process resistant to repudiation.
5) Can a signed document be modified after the signing process?
No. At the moment of signing, TrueScreen seals the document with a digital signature and a qualified timestamp. Any subsequent attempt to alter it automatically invalidates the certification, ensuring the integrity and immutability of the signed document over time.
6) Can TrueScreen digital signing be integrated with existing business management systems?
Yes. TrueScreen integrates with ERP systems, CRM platforms, document management software, HR and payroll systems, real estate management tools, and logistics platforms via API and SDK. Signed documents can be exported in PDF and JSON formats, compatible with all major archiving and compliant storage systems.
