The article “Travellers in favour of body scanners”, published in January 15th 2010 on Skyscanner.net is talking about body scanners that many authorities are planning to install in airports and train stations in the near future.
This will mean that security guards will no longer check you physically, tell you to take off your shoes, belt or other things that you wear and that are looking suspicious to them.
Not surprising then that 2/3 of surveyed passengers liked the idea as it speeds up security checks, but there is still another third against it for health and privacy reasons.
Even if it has been proven that radiation is harmless and privacy is maintained, why is it in that case that so many travellers are against that technology? Probably a fear that their intimacy is violated!
The question is not whether this technology will be used in the future, it is when. The number of passengers at airports and train stations continues to grow, implying that security checks must be accelerated.
If some do not trust the technology or do not want it, traditional manual check will still be available.
