Colm Shorten, IBM's RFID centre of excellence manager, said that RFID technology, which is actually 40 to 50 years old, will not replace existing systems such as barcodes for some time. "Some people refer to it as a disruptive technology, but we believe it will coexist alongside barcodes for at least the next five to ten years."
You can find all the latest information on RFID in ZDNet UK's RFID Toolkit.
The size and shape of the RFID tags vary depending on their application. IBM has developed some tags (such as the white one, third from the left) to be worn around the wrists of hospital patients.

IBM has trialed RFID Portal technology in the Dublin centre to track the movement of devices such as laptops in and out of the office. Devices carrying an RFID tag are tracked as they pass through the portal and an alarm sounds if the action has not been authorised.
According to IBM, similar portals are used in Hong Kong Airport to track luggage.
