Tiny tracking chips called radio-frequency identification devices are being used as pet passports.Soon they will be small, powerful and cheap enough to be implanted into everything form. humans to milkcartons recording and transmitting real-time medical data, or serving as a form. of inventory control.Sensors of every kind, including video cameras, should also become much smaller and cheaper.Forrester Research, a technology consultancy, predicts that 14 billion such devices will be connected to the internet by 2005.

This survey will outline some of main issues, and speculate on the way they are likely to go.
