The section on e-Gates concludes:
64. £9 million has been spent on an iris recognition system which has lasted only six years and its sole value appears to have been that it provided data for the e-Gates. This money could have been better spent on border staff—at least 60 immigration officers could have been employed with the money spent on IRIS. The Committee recommends that, in order to avoid another costly investment in equipment which will not last, the “Agency” publish the data it has collected on the e-Gates trials which it is currently running. The Committee would also like the “Agency” to inform the Committee as to what it intends to do with the data collected by the IRIS programme and whether the retinal [sic] scans will be destroyed following the mothballing of the scanners at Heathrow and Gatwick.
