Apple has won approval for a patent to use infrared signals to send encoded data to cell phones via their cameras. Although Apple hasn’t officially came out and said what they plan to do with the patent, there’s a ton of speculation that Apple will use this to disable phones from taking videos at concerts. From Variety:

The new software, which hasn’t been officially introduced by Apple, would reportedly allow venues to use an infrared beam to disable a mobile phone’s camera, preventing users from taking videos and photos. The development comes as musicians and actors regularly complain about the growing use of mobile phones and selfie sticks at live performances, which allow fans to immediately share content on social media for the millions of people who didn’t actually pay for tickets.
