Sorry but I don’t agree for two obvious reasons… 1st you are asked to provide borrowers with their copy, what about if borrowers call and complain or just a simple call and mentions any document that needs to revise and is told “look in your copies…” and mentions “oh! I was given a USB”… ???
2nd in case you need one sheet from the package you always go to borrower’s copy and replace the screwed one for that particular one… get my point?
I get what you’re thinking but that’s just not going to work.
If you have multiple signing and accidently give a signer the wrong usb you now have privacy issues. I’m sure the signer won’t know how to contact you personally, so they start making calls and complaining about having someone else information and fearing someone else has there’s. Thus the headaches really begin as you now are in damage control for all parties.
Though it sounds like a good idea for saving paper, mix ups and mishaps can happen and you will need a copy from their stack to replace if an error occurs at the table. Maybe putting a name on flash driver corresponding with assignment and making extra copies of NRTC and all docs with signatures and notarizations may work for you.
