While you're correct that the biometric data that Disney collects cannot be used to specifically pinpoint one person, I believe you're incorrect about what the scanner measures.
The *old* finger scanners did indeed measure the size, shape, length, width apart, etc of the two fingers that you inserted into the reader.
The new ones take reading of points on the fingerprint and calculate a number based on it. And because it isn't as accurate as a full fingerprint scan, any number of people can have the exact same calculated number associated with their passes. (I've heard the figure 1 in 100 thrown around) So while it isn't specific enough to link one finger scan precisely to one person (you can't work it in reverse and say "3547648" is Joe Tourist), it's close enough that it's enough of a deterrent for the people selling/sharing tickets illegally.

I stand corrected. I thought I read somewhere that they just incorporated the old tech with the new tech. Thanks for clearing that up.
