The Transportation Security Administration, better known to the common flyer as TSA, is about to make our security check process a bit longer.The TSA will now be checking electronic devices to make sure they are not cleverly disguised explosives. This comes as a larger push from the Department of Homeland Security to strengthen airport security for flights coming into the United States. This means the TSA may ask flyers to turn their devices on and off, to prove they are real. In the event the device doesnt turn on (youre going to want to charge that phone in advance, or bring a battery pack,) the TSA will not allow your device onto the plane and you will have to go through additional security screening. Jeh Johnson, Secretary of Homeland Security told NBC, In this instance, we felt that it was important to crank it up some at the last point-of-departure airports. And well continually evaluate the situation. We know that there remains a terrorist threat to the United States.
