Lapzilla brings word that airports around the US are beginning to use a new type of body-scanning machine which records pictures of travelers underneath their clothing. The process takes roughly 30 seconds, and the person viewing the pictures is located in a separate room. We've discussed similar scanners in the past. From USAToday: "[Barry Steinhardt, head of the ACLU technology project] said passengers would be alarmed if they saw the image of their body. 'It all seems very clinical and non-threatening -- you go through this portal and don't have any idea what's at the other end,' he said. Passengers scanned in Baltimore said they did not know what the scanner did and were not told why they were directed into the booth. Magazine-sized signs are posted around the checkpoint explaining the scanners, but passengers said they did not notice them."
