As an early adopter of the smartphone a Palm Tungsten W I imagined how all of my stuff could now reside within.  Calendar, Contacts, word processor and so much more.  Why not build a device capable of capturing my cards (Front and Back) and present them to the merchant through an NFC interface or a 2D bar code or QR code displayed on the screen?
