Problem with that is that simply pasting your signature is in no way legally binding. Someone could crop your signature out of a random document and then sign a bunch of papers with it.

With a paper copy you're supposed to keep the hard copy (and so is the other party, that's why you always sign in doubles).

Hell even printing, signing and scanning is quite vague in terms of legal value... You'd have to actually send the original hard copies by mail to be 100% covered. (With a registered letter at that).

Digital signing will supposedly make this whole process easier, but doing that digital signing can only be executed by a small amount of certified organisations. (As in everyone can digitally sign something with their own keys, but it won't be legally recognized)

Not a lawyer, just someone who tried to figure out how signing legal documents works to include it in an inhouse program at work
