Under the EU eIDAS Regulation (910/2014), electronic signatures—Simple (SES), Advanced (AES), and Qualified (QES)—are legally binding.
Nota Sign supports all three levels and aligns with equivalent frameworks worldwide, including ESIGN Act (U.S.), UETA, and Electronic Transactions Ordinance (Hong Kong). eIDAS Article 25 confirms that no electronic signature shall be denied legal effect simply because it is electronic or not qualified. Nota Sign ensures compliance across all supported jurisdictions.

What are the risks of non-compliant eSignature solutions?

Non-compliant apps often only paste an image onto a PDF, lacking any authentication, encryption, or audit proof. Such documents can be forged, modified, or rejected in court. Without audit logs or certified digital seals, businesses face:

  • Identity theft and fraudulent signatures
  • Contract enforceability disputes
  • Data breaches and regulatory fines (e.g., GDPR penalties)
  • Reputational damage and operational risk

Nota Sign mitigates these risks by providing court-admissible signature reports that include signers’ identities, timestamps, IP addresses, and cryptographic evidence of document integrity.

Is your electronic signature safe?

Electronic signatures are now essential for global business operations. But not all e-signature platforms offer the same level of legal enforceability, data protection, or international compliance. Choosing a secure, compliant provider ensures that your business documents, data, and digital identities remain protected.
Nota Sign, developed by Fadada, is a global e-signature platform built to meet the world’s most rigorous electronic signature, data security, and privacy standards. It supports regulatory requirements across 100+ countries and regions, helping enterprises “sign with global trust.”

Electronic signature vs handwritten signature

Traditional handwritten signatures can be forged or lost during transit, while Nota Sign ensures:

  • Identity authentication via verified credentials.
  • Audit traceability for every action.
  • Data integrity guaranteed by encryption and digital sealing.
  • Cross-border legal enforceability, unlike paper-based documents that may not meet foreign regulatory requirements.

How does Nota Sign keep electronic signatures safe?

Each document signed via Nota Sign is digitally sealed and tamper-evident, ensuring authenticity and integrity.

  • Immutable audit trail: Every action (view, sign, modify) is recorded with timestamps, IP addresses, and signer details.
  • Certificate-based signatures: Advanced and Qualified signatures use certificates issued by trusted global or local CA providers (such as DigiCert, GlobalSign, Entrust, VIDA, or FPT).
  • Digital sealing with PKI: All completed envelopes are encrypted and sealed using Public Key Infrastructure, providing cryptographic proof against alteration.
  • Compliance assurance: Nota Sign complies with EU eIDAS, U.S. ESIGN Act, and Hong Kong ETO, ensuring legal validity across jurisdictions.
