I usually sign documents on my iPad but in this case they told me the signature had to be from a pen. COVID and everything means I don't have a printer nor a scanner at home so I developed this to "scan my iPad signed documents" worked like a charm!

As a technological toy, I think this sort of thing is cool. In fact, you can do it in LaTeX pretty easily: https://tex.stackexchange.com/questions/94523/simulate-a-scanned-paper https://tex.stackexchange.com/questions/94523/simulate-a-sca... It's interesting that the problem they had was with the signature. You can very easily make a handwritten signature on an iPad. I don't see how there's any practical way to tell the difference between a high-quality, handwritten signature done on an iPad with either a finger or an Apple Pencil and a scanned signature done with a pen. Are you sure that's not just some excuse they gave you?

    Interestingly, there are LaTeX packages for coffee stains[1] and to simulate the variability of an actual typewriter[2]. I suppose both of these involve discrete objects (the coffee stain, individual characters) and photocopy/scan effects involve 'fuzzing' of the whole image, rather than any particular element, and TeX isn't really set up for the former.

What do you use to sign PDFs on your iPad?

  I just use my regular Good Notes 5 app and then export back the PDF
