Oracle Digital Signature capture

have a requirement where I need to include a digital signature in the report. I searched on the google to find the digital signature capturing device and there are a lot of good products in the market but no where I am able to get the integration of this device with Oracle EBS.

PROBLEM STATEMENT : The drivers of the transport (say truck etc) that pick up material from the warehouse to the stores have to sign a declaration of the items they are carrying in their truck, and give it in the warehouse.This is being done manually on papers and due to this the archiving becomes difficult. What my requirement is driver will sign on this digital signature capturing device and capture that signature in the order management attachements
