Cracked Wall Foundation, by PJFurlong06

I found this Lifehacker post this week and I am totally loving the demonstration he gives in his video. Anyone who has watched a crime drama knows that people are filthy beings that leave traces of themselves wherever they go. It could be DNA from skin cells or hair, prints from our shoes, or a heat signature from touching something.

In the video, Mark Rober shows you how an iPhone attachment can pick up the PIN code you just entered into a terminal to pay for goods and services. He even gives you some ideas on how to avoid getting hit.

For those of us that saw Bob Arno at the Community meeting last week and saw the coordinated shoulder surfing, this is a high-tech way to do exactly the same thing.
