Update July 9: The U.K.’s Department for Transport issued a similar warning today, advising anyone flying to or from the U.K. to charge their devices.
If you want to bring your smartphone with you next time you fly into the U.S., you better make sure it’s charged.
The Transportation Security Administration announced some new “enhanced security measures” yesterday on its blog. The new rules specify that “powerless devices will not be permitted onboard” aircrafts. The directive came from Secretary of Homeland Security Jeh Johnson.
Johnson’s decision “followed intelligence that al-Qaida operatives in Syria and Yemen may have developed bombs that could be placed in mobile telephones and avoid detection to bring down aircraft bound for America,” according to the Guardian. The agency did not disclose which international airports are affected by the policy change.
In other TSA news, the agency recently started testing a new ‘Randomizer’ app, which could cut down security lines in as many as 100 airports.
