I’m going to Walt Disney World in just 24 days, for WDW Today Reunion 2013! But I have some concerns about the use of active and passive RFIDs in the new MagicBands, and of passive RFIDs in the resort hotel room keys. So, I’m planning to skip the MagicBand and just stick with the room key, which I can store in this nifty RFID-blocking wallet I just made with a little help from Instructables, a few things I had around the house, and some cute Hello Kitty duct tape my sister-in-law gave me. The RFID-blocking component is aluminum foil, sandwiched between two sheets of duct tape to make the main body of the wallet.
It took about 90 minutes to make the wallet. I think it would go faster next time, since I had a little trouble at first working with the duct tape. The Hello Kitty duct tape was more forgiving than the standard silver duct tape when it came to accidentally sticking things together and having to pull them apart, perhaps because the cutesy patterned duct tapes seem to have been designed primarily for crafting, not taping ducts (which actually turns out to not be a good use of duct tape, nominative determinism notwithstanding.
I might just make a little pouch for Magic Bands, too, but I haven’t been about to find good sources on whether active RFIDs are blocked by aluminum foil; I’m trusting Consumer Reports that the foil blocks passive RFIDs.
And yes, a tinfoil hat will be necessary, strictly for fashion purposes. A project for another day.
