Gizmodo posted this video demonstration of how a thief can use a thermal-imaging camera attachment for the iPhone to possibly steal your PIN code while checking out at a store. It’s cheap and easy for a thief to do, but there is a way to thwart the potential issue — just rest your other fingers on the entire number pad AS you type your PIN. See the video for an example.

Here’s something I didn’t know until just now. Have you heard of ASMR? It stands for Autonomous sensory meridian response and its sole purpose, in as many as 2.6 million different YouTube videos so far online, is to soothe people into sleeping or relaxing through the use of sound. Usually, this consists of crumpling paper or plastic, lightly rubbing fabric along the skin, or tapping any number of various objects against each other. No loud sounds, just constant soft sounds that may put you to sleep. Interesting… So the next time you have trouble sleeping, maybe you should go online and search ASMR videos on YouTube.
