By brolloh We’re getting a little formal at Square HQ today, we have lots of PDFs to sign so we’re using a feature introduced to Preview with OS X Lion – Signatures.
We love how simple and speedy this feature is. To start, open a PDF within Preview that’s awaiting a signature. Select ‘Annotate’ then ‘Signature’ then ‘Creature Signature from FaceTime HD Camera (built-in)’

A new window will launch and you’ll likely see yourself in the video capture window. As the instructions suggest, you’ll need to scribble down your signature on a plain piece of white paper and hold it up to the camera with the blue line directly underneath. You’ll see a live preview of the digital signature so select ‘Accept’ when happy.

Your signature has been vectorised and now sits patiently within the Signatures drop down menu, select the signature and you’ll be required to draw a box where you’d like it to appear.

As the signature is vector based, it can be as large as you require without pixellating. You can add as many signatures as you’d like if you have different versions (or a stage name!)

Simple but such a great feature!
More soon!
