magnetic coin wallets

my friend has an old worn out wallet and twice coins fell all over the place. he doesn't want to buy a new one so i thought to cover the wall of the coin pocket with thin magnet. then i think why not cover all wallets with thin magnet inside to avoid coins drop out the wallet.

award points directly into the credit card

the problem with retailers' cards is that each retailer awards its own card and people end up carrying too many of them. since every retailer accepts credit cards, credit card companies should allow for an additional magnetic bar or chip to be added at the back of the credit card that will store any and all retailer's points (gas station, supermarket, groceries, malls, airlines etc). swipe the card once so that the scanner reads the balance and gives the discount, swipe it once again to make payment.
