My thought is not to add a clock the the RFID puck. It would be to sell a clock that guests could replace the puck with at home. If it were sold separately, there would be no additional cost to those those who see it more as a "throw away", but those who like the band and would like to continue the magic at home could transform their magic band into a watch band at home. I don't visit the parks or ships all the time so I like little things that can help me feel those memories at home.
