Introducing the latest ubiquitous device which is called U biquitous Communicator (UC).
Difference between Passive RFID and Active RFID
Tour guiding system
providing a variety of information rather than only navigating route for the user.

Key element: Are they only used for navigation services?
In the ubiquitous computing environment, many computers and sensors are distributed to the urban environment. It is easy to get information at everytime, everywhere based on the ubiquitous computing and sensor network.
Communication distance between the device and its system (Satellite System, network server and machine) strongly affects t he size of service area.
'SuiPo,' or Suica Poster, which uses a combination of IC card ticket ‘Suica’ and Internet accessible mobile phone. Customers can get e-mail information by touching their SUICA on the reader located near the poster.
