Finger/thumb Print Scanning

When you enter Universal Studios theme park they scan your ticket and also a finger print. They say it’s for security reason but I read that they don’t want you selling the remainder of the multi day ticket pass to someone else and that all scans are deleted in 30 days. They also provide lockers that require a thumb print; no lost keys there. In the not so distant future the punch clock will be the thing of the past when finger print or retinal scans will be the used to monitor check in and checkout times.
