Ink signature (digitised handwritten signature)

An ink signature (or digitised handwritten signature) is the digitisation of the traditional handwritten signature in image form (JPG/PNG) affixed to a document. It constitutes the most basic level of simple electronic signature (SES) under eIDAS: without strong authentication or an audit trail, its evidentiary value is limited. It is however used for documents with low legal stakes (internal signatures, annotations).
