Yes, you can. Disney has made it clear that the current MagicBands (MagicBand 2.0) will continue to be available throughout 2023 and be used for all the normal functions it has always had.
Guests are not forced to use MagicBands while visiting Disney World and there are still many options without using one.
MagicBands use RF technology to send and receive information, which Disney says was built with extensive privacy controls and with guest safety in mind.
