- 1Ubiquitous computing systemsUbiquitous means ‘existing everywhere’. Processors can be embedded in any device,
including clothing, appliances, vehicles, buildings and people, to connect them to the
internet so that the data generated by the processors will be readily available. - 2Radio frequency identification (RFID)Currently, objects within a ubiquitous computing environment usually contain radio
frequency identification (RFID) chips. RFID is a technology that uses radio waves
to transfer data to a tag on a person or an object so that the person/object can be
identified and tracked. These tags contain information that is stored electronically and
which can be transmitted. It is similar to the bar code systems used in supermarkets,
but unlike a bar code, RFID does not need to be scanned. An example of a use of RFID
is the cat flaps that only open for the animal that has the correct chip in its collar. - 3Applications of ubiquitous computingCurrently, there are computing systems in place which monitor the shelf and
warehouse stock. This technology is used by many industries (supermarkets, book
and DVD suppliers, car part manufacturers, etc). When the stock reaches a certain
minimum level, an order is automatically placed with the appropriate supplier
electronically. Mainly this is done by a process where the tills feed product sales to a
central computer, which then calculates the present stock. Currently manual checks still
have to be made to allow for ‘shrinkage’ (i.e. loss due to theft or damage).
