Barred for refusal

I was shocked to read that "Two women, one a Muslim, have become the first people to be barred from boarding a flight because they refused to go through a full-body airport scanner.
Manchester airport confirmed today that the women, who were booked to fly to Islamabad with Pakistan International Airlines, were told they could not get on the plane after they refused to be scanned for medical and religious reasons."
I had assumed that one could either be scanned or opt for a physical search But, apparently, "While American transport authorities offer passengers a choice between going through the full-body scanner or going through a metal-arch scanner and a physical search, the British government has said that a refusal to go through the body scanner would bar passengers from boarding aircraft."

Now that scanners are a part of everyday life, what do the rabbis have to say about the new technology? If you have discussed this with your rabbi, I would love to hear from you.
