Buying things with your mind

How would you like to go through the checkout at your favorite store and never take out a credit card or cash. I have an idea that may make that possible. Ok, you go to the clerk, they scan your item put it in a bag, then tell you the total. Now all you got to do is stare at a screen with numbers and letters and whatever number or letters you stare at will be your password. This can be done with a program that can look at your eyes, or see your brain impulses, and this unlocks your bank account info. Now stare at what account you want the money deducted from, and if it is accepted, thats is. No fuss, no muss! I think this is a pretty good idea, that removes cash, coins, and checks from our pockets. Don't even get me started on the evil credit cards!

Is this just an idea of yours, or do you have a source for the idea?

I personally don't like the idea, because as much as my mind wanders, I'd either give my account info out to someone, or I'd be buying many things I didn't need...

Ya know, impulse buying is a *you know what*.
