My wife and irecently hit an antiques-and-junk store, an enormous warehouse with individual dealers in rented booth spaces and a quirky little cafe in the back corner. As we sat slugging down rose tea and sharing a piece of Snickers~® cheesecake, the conversation turned to the coin collection my granddad sent me a few weeks before: Israeli and Roman coins from 1600 years ago. My wife wondered how "arphids" (radio frequency identification tags) might one day play out in such a collection.rnThese days arphids don't do much. They just bark serial numbers to a database when hit with a radio wave. But as memory on the chips gets cheaper and bigger, as technologists predict will happen, arphids will come to contain the very databases they have in the past just referenced. That means everything gets smart.
