In my system I had a container field in Staff card for this signature which would then be placed on Time Card, NDA, and other document managed by FM.
I do not know if they will stand-up in court if there was ever a legal battle, but for the last 20 years it has never been an issue.
But now I have clients who's staff are not comfortable with their signature being stored in FM.
Therefore I was thinking of having FM create a signature similar to Adobe, something with their name, and randomly generated serial number and some legal-looking watermark.
Curious if anyone has opinions on the best way to implement something like this?
