Imagine the possibilities when sensors and RFID tags are cheap enough to justify putting them on almost anything you might like to track -- food, waste items, any and all retail products for inventory management & automated purchasing, and of course human beings, for monitoring vital signs, to expedite emergency response, etc.
At a higher level of sophistication, where the "thing" has some intelligence built in, we have other possibilities like intelligent vehicles & roads that communicate with each other to improve safety and minimize traffic congestion.
Those are just a few examples of the possibilities, but there are many more.
Can anyone explain what the Internet of Things is actually for? There's a lot of hype that the IoT is going to be the biggest thing ever, but the only things in my house that would benefit from internet connectivity are my electricy and gas meters; that's hardly going to result in a massive market.
