Businesses today are more automated than ever. Companies are replacing traditional paper-based signing processes with electronic and digital signature technologies.

Electronic and digital signatures

An electronic signature is a general term for any electronic process that shows agreement or approval. It includes different methods for signing documents electronically. For example, a signer can use an image of a handwritten signature. Electronic signatures are easy to set up and simple to use.

A digital signature is a type of electronic signature with additional security features. It verifies the signer’s identity, protects document integrity, and helps prevent fraud. Digital signatures use encryption to create a unique digital certificate for each signing process. This certificate securely links the signer to the document and records all related actions.

The signer must have this certificate to sign a specific document. As a result, unauthorized changes become extremely difficult. Digital signatures provide a high level of security and trust for electronic documents.

The main difference between electronic and digital signatures is security and intended use. Digital signatures use cryptographic technology to verify identity and secure documents. They are often required for regulated or high-trust transactions. Electronic signatures are more commonly used for everyday business documents that are legally accepted in electronic form.

Types of signature

The types of electronic signatures are determined by the laws of a specific country and vary across jurisdictions. For instance, eIDAS Regulation recognizes the following signature types:

Types of signatures

The types of electronic signatures depend on the laws of each country and may differ across regions. For example, the eIDAS Regulation defines the following signature types:

• Simple electronic signature
  A basic signature method that uses an email address or a one-time access code for confirmation. This type is suitable for everyday business transactions.


• Advanced electronic signature
  A signature that requires additional identity verification. The signer may receive an access code, provide a government-issued ID, or use biometric data. The system then generates and attaches a digital certificate to the transaction.


• Qualified electronic signature
  A signature that complies with EU Regulation No. 910/2014 (eIDAS) for electronic transactions in the European Union. It provides a high level of legal assurance and supports long-term verification of authorship in electronic data exchange.

Always check the laws and regulations in your country to understand which electronic signatures are valid and how you can use them in your specific case.
