Most of printed documents nowadays don’t need physical signatures from people but they have digital ones already just like welcome letters from banks. But even though everything have evolved to more digital scale, some still remain using the old fashion way of claiming responsibilities on the printed documents. Some still use their signatures while others use it with a custom rubber stamp.
As for me, I still use my own signatures. I don’t do digital signatures on legal and public documents. I only have digital signatures on my blogs but not in all. I just leave the blogging platform to put the words “Posted by Admin” on all my posts.
