- Trials of ID cards have revealed problems with the scanning systems central to the project, it has emerged. It was harder to scan the irises of black people and over-59s. And some fingerprint scanners did not work with large fingers.
- Some experts argue the technology may never be good enough. Professor Angela Sasse, a biometrics expert who has advised MPs on the home affairs select committee, said biometric technologies were "a lot less mature" than manufacturers made out. "To be honest, I think it is a possibility that eventually we will conclude it isn't good enough or that the current systems we're using aren't good enough for a large scale public domain application such as an ID card," she said.
- Serious doubts are being raised about a new secure identity system being incorporated into new UK passports from the end of 2005. Biometric facial recognition will be brought in as part of an international agreement to target terror and fraud. But trials suggest the technology has a 10% failure rate, the BBC has learned. Some experts say the technology could be unsuitable for the high volume of travellers it will deal with, and may fail to improve airport security.
- Concerns have been raised about the ability of biometric technology to cope with exceptional cases - such as someone with very long eyelashes or an eye which is out of focus.
- Long eyelashes and watery eyes could thwart iris scanning technology used for the government's ID card trial. "The pundits tell us that we should expect 7% across the board to fail with iris recognition, mainly due to positioning in front of the camera," project director Roland Sables told MPs. Others are due to eye malformations, watery eyes and long eyelashes in a small percentage. Hard contact lenses could also prove problematic.
- Home Affairs Select Committee member Bob Russell said, "I think this [iris scanning] is going to cause serious problems for people who suffer with bright lights and people with epilepsy. I think it will be necessary at every machine to have at least one member of staff who is a qualified first aider to a high level. I can see people keeling over with epileptic fits."
- People with faint fingerprints will be unable to register on the system, as will manual labourers, particularly those who work with cement or shuffle paper regularly, a committee of MPs was told by Roland Sables, project director of the Home Office pilot scheme.
