The email has two information sections.
The first section is your information (the winner). Then after that there's another section where if you want to transfer it to someone you know, you supply their information as well. It's basic info (name, DOB) and your NYCC ID/Barcode #. That's how they verify I guess that you have a badge for that day.
A friend transferred her Person of Interest signing to me. I haven't received anything yet though but you had until 5PM today to send all the information back to them.
