[Koha] e signature & Koha

Dear List, to make the process of circulation easier and faster, to reduce the usage of paper we had obtained a WACOM e-signature device and our patrons are signing on the pdf version of the slip. All our attempts to "insert" e-signature produced by WACOM directly into Koha failed! Can anybody advice us is it possible to connect such devices directly with Koha? Thanks, Erlanda
