What will RFID mean? Is it a wave of machine to machine communication, though this is discounted as too expensive, especially in the short-term. The alternative is machine to object communication, according to Mark Roberti, editor of RFID Journal:
The costs associated with requiring machine devices to actively transmit data about their status back to another machine (power, broadcast, etc.) will likely limit the deployment of that type of communication to contexts where fluctuations in data are extremely valuable in-and-of themselves. Using low-cost transponders to passively monitor changes in the status of objects will become far more common and important, Roberti argues.
This is all part of the internet of things, though on this plan, we will live in a world of sensors.
