> I suspect this was inevitable given Disney's obsession with removing friction. Yeah, I would say it's this 100%. Disney wants people to leave their wallets at their hotel. The RFID band they give you can be used for everything from entering your hotel room to getting into the park and your rides (including Fastpass) to even paying for things if you link a credit card. Obviously, it's easy to take the band off and give it to someone else, so they needed some other way to check if you're the person who originally used the ticket. Hashes based on fingerprints are unique enough to be the replacement to traditional IDs.
