Paypall eWallet - This concept was designed for a feature in Mobile PC magazine which featured devices of the future. A fully digital wallet that retained all your acount information, passport, driver's ID, and personal photos, it is activated with thumbprint recognition technology. It also ballences your accounts automatically and bills can be paid from it wirelessly. If lost (or stolen) the whole thing can be deactivated, a new one purchased, and resynced at home without ever going to the DMV.
