Both forms of signature stand as lasting records of the signer’s intent, which is typically expressed as the intent to comply with the terms of the signed document.

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.

What Are Electronic Signatures Used for?

  • Onboarding and Account Openings
    The ability to onboard customers from anywhere, at any time became a competitive advantage in the last several years. Since the release of that report and the implementation of COVID-19 social distancing measures, the need for a remote onboarding and agreement process has grown from a competitive advantage to a business necessity.
  • Consumer and Commercial Lending
    The most common areas for electronic signature in lending are consumer loans, small business loans, and retail finance. Electronic signatures, e-forms, and digital processes are being used online, in the call center, and in the branch to expedite the agreement process. 
  • Wealth Management
    Electronic Signatures can shorten the long Wealth Management sales process typically involving multiple meetings and frequent document errors. With electronic signatures, this process can be shortened to just a single session where the paperwork can be processed face-to-face with the customer. However, the wealth management industry is undergoing rapid changes in response to COVID-19. According to an Aite Group survey of wealth management firms in North America, Europe, and Asia, more than half of respondents saw a significant increase in clients requesting digital interactions. Those interactions can be facilitated by electronic signatures.
  • Residential Mortgage
    As more mortgages and refinances move online for increased convenience and speed, electronic signatures are the ideal solution to bring the digital experience into the customer’s home and make it convenient, secure, and compliant. Non-bank lenders have been able to reduce the lengthy mortgage process by more than half, from 45-55 days to fewer than 20.
  • Commercial Banking and Treasury Management
    No two commercial banking clients are the same. As a result, most processes involve ad hoc, customized agreements and contracts. Many of these require signature authorizations and approvals for processes such as new service agreements, ACH authorizations, wire transfer agreements, and applications for corporate cards. Bank representatives can get up and running in minutes with a web or mobile e-sign application to ensure agreements can be enacted the same day they are requested.
  • General E-Contracting and Other Ad-Hoc Processes
    Outside of commercial banking, there are many other ad hoc processes that require signatures in the banking world, including e-contracting and procurement, HR, IT, Legal, Corporate, and more.

Does OneSpan Sign support Qualified Electronic Signatures?

Yes. OneSpan Sign provides a solution for Qualified Electronic Signature (QES). We facilitate legally binding Qualified electronic signature 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 electronic 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
