Handle the Signature callback





When the system requires a signature, the PED displays the relevant data and the shopper can sign on the touch screen. The system invokes the tenderCheckSignatureCallback to allow the store assistant to accept or decline the signature.

Trigger this callback by creating a tender with the tenderOption receiptHandler.
