Biometric Scanners at Typhoon Lagoon

[Nabas]

We visited Typhoon Lagoon recently and they didn’t use the biometric scanner. We thought this very strange since Disney used them everywhere else.

Does anyone know why they weren’t using them at Typhoon Lagoon?

Is it a suntan lotion thing (I.e. lots of people with lotion on their hands smearing the scanners) or something else?
