1B was one of the questions that convinced me that the Congressional staffer did absolutely no research beyond reading the NYT article.I love sec 1b!
If you opt. Out will you have a disadvantage and have to wait in longer lines?
The obvious answer to the question is that the person might have to wait in some longer lines.
Using the RFID card instead of the band will reportedly limit you only to the passive RFID chip and not the powered one. That means that the card will be good at FP returns and paying for stuff, but won't be able to be picked up by the 'non-touch' scanners. This might result in the holder not getting some push offers like FPs and, therefore, waiting in some lines longer than he otherwise would have. Cinderella also won't know who he is.
