As of now, there are 40 scanners in use. However, TSA has spent an additional $25 million on another 150 scanners and has plans to buy more in the future.
These machines will take airport security to a new level. The scanners are able to use a type of x-ray device to make a detailed image of a passengerâs body. This will enable security officials to see explosives underneath clothes, but this is also where the notion of imposing on personal privacy comes into play.
However, according to a USA Today poll, air travelers are in support of the government’s body scanners at airports, despite the fact that they may impede privacy. This poll revealed that for most people, the enhanced security these scanners provide outweighs any privacy issues.
