What is an electronic signature?

Electronic signatures are a legal concept, much like their paper equivalent, and defined by the US Federal ESIGN Act as ”an electronic sound, symbol, or process, attached to or logically associated with a contract or other record and executed or adopted by a person with the intent to sign the record."

The function of an electronic signature is to capture the intent of the signer to be bound by the terms and conditions in a contract. E-Signature software is designed to capture legally-enforceable signatures online.

Are electronic signatures legally binding?

Yes, OneSpan Sign’s electronic signatures are legally binding and enforceable in countries that have enacted e-signature laws.

Electronic signatures created using our solution comply with both the U.S. ESIGN Act and UETA. OneSpan Sign electronic signatures also comply with Regulation No 910/2014 on Electronic Identification and Trust Services Regulation (eIDAS) in the European Union. 

For a legal opinion on the enforceability of e-signatures in any given country and any local data residency requirements, consult your legal counsel.

E-Signature FAQ

What is the difference between an electronic signature and a digital signature?

Though related concepts, digital signatures and electronic signatures are different. An electronic signature is a legal concept. Its captures a person’s intent to be legally bound to an agreement or contract. 


However, a digital signature refers to encryption/decryption technology within an electronic signature. Based on public-key cryptography, digital signatures secure signed documents and allow one to verify the authenticity of a signed record.


In short, a digital signature cannot capture a person’s intent to sign a document. When used with an electronic signature application, digital signature technology secures the e-signed data.

Does OneSpan Sign support Qualified Electronic Signatures?

Yes. OneSpan Sign provides a solution for Qualified Electronic Signatures (QES). We facilitate legally binding Qualified E-Signatures through our partnerships with Qualified Trust Service Providers. 

A Qualified Electronic Signature is created using a digital certificate (known as a qualified certificate) assigned to an individual. Think of it as the digital equivalent of a government-issued identity card or passport. 

The qualified certificate and associated key must be obtained from a Qualified Trust Service Provider or Qualified Certificate Authority. It is provided to the individual on a smart card or USB device. That person must connect the smart card or USB device to their computer or mobile device when signing a document, and must enter at least a user ID/password to access their qualified certificate.  

OneSpan Sign fully manages the use of a qualified certificate during the e-signature workflow. For example: 

  • The signer must enter OneSpan Sign by successful authentication
  • The signer e-signs the document 
  • Their electronic signature is secured using digital signature encryption (the digital signature is created using the qualified certificate and associated key) 
  • This creates a Qualified Electronic Signature
