Purchases

I would love it if there would be a way developed that would make it possible for me to make purchases just by having a machine scan my eye or hand print. I think this would not only cut down on identity theft but also just theft in general. It would be great to go to Wal-Mart and not have to worry that my purse, with all my money, debit cards and credit cards, will be stolen. The one thing that I hate about going on vacation is I have a fear of leaving my purse in the hotel room ( I guess I have seen one to many Datelines) fear that the cleaning people will steal from me, so therefore I am left packing around a heavy purse all day.
