Fingerprints are unique

On a recent trip to the Statue of Liberty in New York, I was amazed by some new technology that I witnessed there. As it turns out, in order to enter the statue itself all personal items like shopping bags and purses have to be stored in a locker area. I was really surprised to learn that there were no keys to carry or combinations to remember, rather the locker was locked using a single fingerprint. It is scanned in the computer and you are assigned a locker number and scanned again in the end when you are ready to leave. It seemed strange that in order to retrieve our belongings (which only consisted of my daughter's treasured Hannah Montana purse) all we had to do was hang on to my husband's finger. That proved difficult,however, after I threatened to chew it off when he left me alone and rushed off to the top to see the view...
