conducted by family members or people the parents trust, and chances are that the children would be too far away from the range of any RFID reader for this technology to be truly lifesaving. Therefore, it is not unrealis- tic to state that, in some cases, the business plans of companies offering such tech- nologies are many times largely based on promoting fear. Still, as in the case of lost pets, there can be great value in embedded identification for recovery of loved ones.) Chipping senior citizens can give hospitals immediate access to their medi- cal records. Many wealthy individuals are getting themselves and their children chipped for security reasons. Large herds of cattle and sheep are implanted with chips to assist ranchers and farmers with efficient tracking. Yet another implant is an RFID biosensor that is being developed for diabetics. An incredible implant called a diabetes infusion pump is expected on the market within 2006. An even more dramatic breakthrough is being developed: an implant- able pump with a biosensor that monitors blood glucose and continuously pro- vides the right amount of insulin. RFID and chipping are used for banks, gas stations, hospitals, drivers' license branches, schools, the military, automobiles, telephones and mobile phones, televi- ICT Trends Driving the Broadband Evolution xliii sions, computer systems, prisons, governments, workplaces, corporations, bars, res- taurants, and private clubs-in other words, they are everywhere. Intelligent Wearables The evolution of wearables is truly an exciting frontier. Steve Mann, a professor at the University of Toronto, is an advocate, and arguably the founder, of the field of wear- able computing. Beginning with his early work in personal imaging, Mann has been involved intimately with the study of wearables for over two decades. From the early 1980s to the mid-1990s, his devices were functional but bulky and awkward. By the late 1990s, his intelligent wearables could pass for a pair of sunglasses and a mobile phone.
