Not sure how long it's been there, but the following disclaimer is now found on the Magic Bands and Cards page of the MDE website, if you're logged in and have the ability to customize MBs:
The MagicBand uses radio frequency (RF) technology and can be read by short and long-range readers located at the Walt Disney World Resort. If you prefer to use an RF card, which cannot be detected by long-range readers, you can request an RF card at your Disney Resort hotel, and you do not need to customize your MagicBand.
Not sure if this is the same as a card for your AP or ticket but I would request one anyway, if for nothing else than to keep as a backup in your wallet.
