Legally, a Signature Is Any Mark Intended As An Identification & Assent: So Digitize.

Digitize Your Signature and Email Instead of Fax

The biggest source of paper in my work life is contracts and client agreements that need to be signed and returned. While people generally say "sign this and fax it back to us," you can do it without getting paper involved. First, create a digital version of your signaturewith a transparent background. Then, get the documents via email, and email (or eFax) them back with your signature added to them. (While there are lots of different kinds of electronic and digital signatures, this type will work for common consumer scenarios. It won't work if you need something notarized or to appear with an original signature.)
