How it works Our software utilizes an algorithm that allows you to digitally draw your signature with your mouse or fingers on the canvas on your mobile phone, tablet or computer in real time. Handwritten signatures give a sense of natural signing of documents similar to physical signing and generally guarantee the authenticity of the signatory rather than just typing the letters into text fields. The electronic signature can be attached to any PDF available in electronic form. You can create an electronic signature and eSign PDF documents from any device, from anywhere and at any time. After you have created an e-signature and selected a PDF file to eSign, you will place a marker on the spot where you want the signature to be added. The signature will be adjusted to the size of the original PDF file and will have a transparent background, which makes it a perfect overlay and gets your work authenticated with your personal data in digital format. Examples of PDF files e-Signed in real time with handwritten signatures Electronic signature vs. digital signature Other than dealing with electronic signatures, also consider creating a digital signature for digitally signing a file to ensure the integrity of the message being sent or the file being shared and to ensure the authenticity of the sender of the message. Learn more about the difference between an electronic and a digital signature. One of the great examples of using an electronic signature is creating a digital business card. Combined with digital signatures, these business cards are used to introduce companies and individuals to the business world and connect with other cardholders within the same or related business area.
