Parents digitally signing a letter
We've been asked to investigate the possibility that letters on our parent portal (for trips etc) that require signing could be done digitally for parents.
So instead of them downloading and printing the PDF and sending it back to us by post or their child, they view the document online, sign it and send it back digitally.
It needs to be something that is stored centrally, unlike eSignatures from Adobe where you upload a document and it emails it to recipients.
Is this possible and if so, what are the costs and requirements?
