When a party is invited to sign a document where Signature fields has been added, the party has the possibility (this can be set as mandatory or optional) of drawing a hand-drawn scribble as a signature. Currently, a new update is being rolled out in eSign Online where two additional options are added for signing parties when it comes to Signature fields. You can read more about this launch here.
With the new update, it is possible to add a typed signature where the signing party simply types their signature and choose a text font to display the signature with, or, the signing party can choose to upload a picture of their signature. See images below.
