Well, I'm no good at sappy hello's, so I'll just say this: I need your help. See, I'm in the business of understanding things that interest me. As of now the intricacies of how a RFID chip works, and can be manipulated by an individual is one of them. To extenuate, I have no idea how when the receiver gets the signal it "reads" it, or what it does with those strew of lines dotting it. Also, how can Aluminum foil block radio frequency waves? Someone said that on this forum. Second is how EMP works. What is it, how can it be controlled and built safely by an individual. What are its uses. Third and last (as of now, can't overload y'all ) is how X-ray machines work in regards to how to hide objects in there. I know that the objects are colored three colors representing: metal, inorganic, and organic based off of density. However, I'm not sure how to hide a metal within another inconspicuous object. All in stated no ulterior reasonings, I just like to know and feel that if something is "taboo" and shan't be known then... I can't even begin in the moral and intellectual depravity the society would have to accept. Mind you I have a basic understanding of both RFID and X-Ray, but it is all self-taught so there are probably gaping holes of logic and I would LOVE any help in aiding me to understand. EMP... I'm not so shabby on... yet! Good night and stay classy.
