Don't Mix Up an Electronic Signature and Digital Signature

There are two ways to insert signature in PDF: electronic signature and digital signature. 

An electronic signature is actually a signature image that you create by yourself or use a scan from an existing document. An electronic signature is suitable for those types of documents in which you don’t need a high level of security:

  • for signing presentations, books, and copyright materials
  • to sign a non-disclosure agreement for employment
  • for printed materials — business cards, booklets, catalogs, etc.
  • for signing emails

Digital signature is the advanced and secure verification of the sender. It requires a certified digital IP and PIN to prove the sender’s identity. Document and signature are encrypted and bound with electronic proof seal. Digital signatures are commonly used for software distribution, financial transactions, contracts and other cases where it is important to detect forgery and tampering.
