We went 10 days between June 23 and July 6th and were never asked to sign our tickets. We all bought legit unused tickets from a reputable third party seller and we would never try to beat the system. I think it would be extremely foolish to buy the "unused" portion of a ticket hoping to show up and use it, but IMO, the finger scanning is more show than an accurate device. I'm sure it's productive in reducing ticket swapping because people think they're being monitored.
