Virtual signing is a great shortcut, especially when you have many documents to sign. Firstly, be aware that there are two completely different signatures: electronic and digital.

An electronic signature is a broad category, which includes just a simple image of your signature, whereas a digital signature is far more sophisticated and secure.

A digital signature is your identity, which is cryptographically attached to a document and cannot be forged. Do not confuse these two since this article is about electronic signatures, which are more for personal use.

Adobe Reader will ask you to type your name. You can choose this option as a signature, but this is probably not the best way, since Adobe Reader will just convert your typed name into a signature. Nevertheless, try it first, as it might fit your needs. The “Image” option allows you to upload a scanned signature image and import it to Adobe Reader as your signature. You can also use the “Draw” option. Click the “Draw” icon.
