PAN technology has potential applications in business, medical, retail and even in personal arenas. Business associates could, for example, exchange electronic business cards with a handshake. Corporate security devices could automatically log users on and off computer systems and subway commuters could pay for a ride by walking through a turnstile.
PAN technology could also enable people to carry digital versions of their medical files for instant access by emergency medical technicians; calling card numbers could automatically be send from a wallet to a payphone; and ATMs and automobiles would be able to immediately distinguish their owners as they approach. Even household devices, such as CD players, televisions and toasters, could identify and adapt to individual preferences and tastes using PAN technology.
