Idea: Remember the lines from Seinfeld? George: "Because important things go in a case. You got a skull for your brain, a plastic sleeve for your comb, and a wallet for your money". Nowadays in addition to cash, you need to carry multiple credit/debit cards in your wallet. How about a cellphone which can be programmed to provide an interface to all your credit/debit cards? For example, your cellphone could have an interface to use each of your cards, and once you select a card to use, it sends an encrypted SMS to the shop. Instead of swipe machines, the shop could have smart SMS readers who can decrypt the message and use the card information from the message towards the customer's shopping cart.
Reward: No need to carry physical cards in your wallet. Remember? Jerry: [referring to George's stuffed wallet] "Your friend is morbidly obese".
Bonus: Secure shopping! Since you don't need to carry your credit/debit cards, your shopping can be really hassle-free.
