Touch-Screen Ticket Kiosks
Self-serve kiosks are great time-savers for checking in and printing boarding passes at airports and train stations. Unfortunately, they aren't health savers, as they are also covered in germs. An ABC affiliate did a test of public touch screens and found that an Amtrak check-in terminal at Union Station contained a reading of 3,700 colony-forming bacteria units (CFU) per swab. It's not all bad news, though, as a Delta check-in kiosk at Reagan National Airport only contained 10 CFUs. Wash your hands or use sanitizer after touching the screens.
