Tech Quiz on "smart guns". How smart are you? :: 02/04/2014

"It's the kind of technology you'd expect Q to present to 007 just before he rushes out the door to track down the latest villain. But this new gun is pitched for the everyday users, not just international spies. The Armatix Smart System consists of a gun and a watch that have to be within Radio Frequency Identity (RFID) range of each other to work. Essentially, without the watch, the gun is no more dangerous than a paperweight."

Now that you've read the lead in, and the article, can this gun be defeated by spurious EMI or RF signals? Magnetic fields? Dead batteries? Dumb owners who forget to wear the watch? If you fail this quiz, shame on you.
