Before you leave another cast member will show you how to use the new pass and will make sure that your biometric data is in the system. The next time you head to a park a cast member will direct you where you should go. You will then hold your ticket to the scanner and place your finger on the pad. When the light turns green, you're in.It's my impression that Disney does this mostly for the purposes of making sure that discounted longer-term passes aren't shared among different individuals. It's not hard, however, envisioning that this might point the way toward future security applications.
