What is radio frequency identification? |
Currently, objects within a ubiquitous computing environment usually contain radio 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. |

What can applications of ubiquitous computing be used for? |
Currently, 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). However, there are now experimental systems involving products which contain RFID. The RFIDs register when any product leaves the premises. |
