Am I able to put my digital signature in a document? If so, then how?

Now... I'll let you in on a little secret... If you REALLY want to add your signature into your Pages document, there is a way that you can do this without having to PDF your documents or use another other 3rd party app. It's called ⌘Command+C and ⌘Command+V.

Bacially, after you go through the process of saving your Signature using Preview, all you do is highlight the signature that you've made or would like to use, use ⌘Command+C to COPY this signature and then ⌘Command+V to PASTE into your Pages document. It would then create an "image" of your signature, which you can then move and size wherever you please in your document.

Not sure if this has been said already, but wouldn't it just be the easiest thing to export your pages doc into PDF for and add the signature within Preview?

You can add a digital signature to a Pages pdf in Acrobat Pro.

There used to be a catch in Pages '09 that there was a white base layer to each page and therefore the digital signature had to be one layer higher. I don't know if this still applies in Pages 5. Be worth experimenting.

Meanwhile just treating it as any other graphic within Pages seems to work fine.

In pages in iPad create a document then send a copy to Adobe Acrobat as a pdf. Then in Adobe Acrobat, using the pen function make your signature. Then share the file as a 'Flattened copy', and the copy will retain the signature.

Further, since they bothered to create a Signature function in Preview, why not make that available to other applications? At least their own word processor??
