Reasoning In the wake of security concerns and the ever-increasing numbers of flying passengers - more than 90 million passengers pass through UK immigration each year - new ways have been sought to recognise passengers who may have a criminal record or are considered ‘undesirable’. The use of fingerprints is messy and time-consuming, and is not always accurate. A method that has been on trial since 2002 is the ‘Iris Recognition System.’ This method takes a digital image of the iris patterns on the back of the eye and compares it with those that are already stored in a databank. This system has proved to be 100% accurate since no two irises have exactly the same pattern, not even those of identical twins. Even the right and left eyes of the same person do not exhibit the same pattern. It is believed that the new method will help to speed up the immigration system as well as make it more secure.

203. It is believed that a new way of recognising previously identified terrorists could speed up the immigration process and make it more accurate

204. The 'Iris Recognition System' is not as accurate as the use of fingerprints

	(a) True
	(b) False
	(c) Cannot say
	(d)

205. One problem with the ‘Iris Recognition System’ is that it cannot distinguish between identical twins

	(a) True
	(b) False
	(c) Cannot say
