You can check the schedule for rolling them out; right now it is just at DVC.
However, the RFID technology is being used at POR on the KTTW card, so you can still go through the new entrances.
Pretty cool, but I had a major breach with my card that was reported up through IT management at POR two weeks ago. It is not without its bugs, so do not wish the bracelets are rolled out. There are still issues.
