In FL a signature stamp is acceptable if the notary has a physical limitation and notifies the SoS in advance. Here is the statute.
“A notary public may not sign notarial certificates using a facsimile signature stamp unless the notary public has a physical disability that limits or prohibits his or her ability to make a written signature and unless the notary public has first submitted written notice to the Department of State with an exemplar of the facsimile signature stamp.” Fla. Stat. § 117.107(2).
