ID cards and implants: convenient or a step too far in the invasion of our privacy?

If you could have a chip implanted or carry around an ID card that meant you never again had to prove your ID, remember logins and passwords and so on, would you do it? That's the question we put to more than 4,000 visitors to techadvisor.co.uk, and the results might surprise you. Also see: How to protect against identity theft - 9 golden rules

Fifty percent of the 4,087 respondents to our survey would not be willing to have a chip implanted or carry around an ID card in return for this freedom.

"I do not have to be doing some thing illegal to want aspects of my private life to remain private," wrote MechKB 2. "We already have controversy over GCHQ monitoring various aspects of technology using the excuse of combatting terrorism, so do we really want chips that allow even more governmental intrusion into our lives?"

"We all have some form of ID, but we do not have a legal requirement to carry it at all times. If it gets to the point that it becomes a legal requirement to carry ID at all times then, sorry, but the terrorist has won," added carver.

Perhaps more surprisingly, 39 percent of respondents would be willing to carry an ID card or be chipped. See also: No-one cares about privacy anymore

"I really don't see anything wrong with having a specialised ID card, as long as it doesn't become a legal requirement that I carry it at all times. I still believe that I should be allowed to move freely around in my own country without having to identify myself to the authorities.

"And that's where the problems arise - if I can do it, so can anyone else, and not everyone has as much right to be here as me, or is as harmless as me when it comes to posing a threat to society," said Forum Editor.

Other respondents suggested that carrying an ID card or chip would ensure you are identified if you require medical attention or the worst should happen. "As I walk to the local shop with only loose change in my pocket, I often think: 'If I went down now, and was found laying there, I could be completely unknown.' As we get older the chances of this happening increase. At 81, I know I should carry ID at all times," said SparkyJack.

Having just one form of identity could also be more convenient. "Currently having to deal with a death in the family, I am sick of quoting numbers to various departments over the phone - NI number, NHS number, holder numbers, contact numbers… We need one number to rule them all, issued at birth and implanted and encrypted so all I have to do is wave my hand at or walk past a scanner to be identified," said Fruit Bat /\0/\.
