Radio Frequency Identification (20 May 2004)
The information they contain - an electronic bar code - could change the way we shop. One possibility is to banish queues at the check out - the RFID tags could be instantly read so adding up the cost of our shopping in seconds. But the information they store could also, in theory be read by others. If these tags are set to be on manufactured goods, credit cards and even money, what will they communicate about us to others who want to read the information?
Quentin is joined by Jason Brotherton from the University College London Interaction Centre and by Dr Duncan Macfarlane, Research Director of Auto ID Centre in Cambridge, to find out how RFID tags will work, when they might be in our shops and whether they will threaten our privacy.
