While I can absolutely understanding something like this Card Case app from Square raising the ire of luddites everywhere I can't help but be smitten with it. The app allows you to walk into any merchant using the Square device and use voice verification to make your purchases. Privacy concerns, potential hacks and Big Brother style conspiracy theories aside this is the stuff that proper Science Fiction dreamed of years ago and we're actually seeing it happen. Pretty phenomenal if you ask me. Watch the video.
