re: Fingerprinting at Disney World

I was at Universal in January. 3 day pass. I knew what the fingerprint was for, but with all the people coming thru, I figured it was more of a scare tactic and it couldn't possibly work. On the second day at opening, rush of folks thru the gates, I purposely put down a different finger (index first day), tried thumb second day. They stopped me and I told them I couldn't remember with finger I originally scanned. After purposely scanning 2 different fingers and being rejected, I gave them the index and I was allowed to enter and spend my $$.
