Near Field Communication (NFC) allows two devices to exchange information within close proximity of each other (a few inches). It is expected to become a widely used system for making mobile payments by smartphone. So no more plastic, just wave your iPhone or Android in front of an NFC reader to pay for that chai latte (and this is just the tip of the iceberg, there are far more cooler applications than this). The potential of NFC is big but somehow the NFC-obsessed Seth Planck of NFC Rumors has put it all into one beautifully rendered infographic he called Frictionless.
