Reinventing the supermarket

Imagine an itunes not just for music, but for every real world physical item sold on the internet, with payement as simple as dragging the item (from the ipad folder view with horozontal scrolling super panoramic web page) into a trolley, the trolley to a checkout, and virtual notes and coins into the "register" to pay for it, all gestures without a single number or letter having to be typed. When it comes to securing data, you can't get more secure than to turn everything into finger movements. You could even authenticate payments and refunds the finger print reader or biometric authenticator that is the facetime camera- completely reinventing the store, the shopping mall, ebay and paypal in one go. How easy is that? Even changing currency a blast, and fun to use, just rotating in and out different coin and note dispensors. Not everyone with good ideas have the money to patent it. That companies don't embrace and look after such people really *****.
