RFID and the devil
I suspect all of you have heard the argument that RFID implants are the work of the devil, mark of the beast and will surely bring about our destruction. That is, of course, unless the government uses them to track you down first. Perhaps it is a waste of time to argue with people who believe this but I want to hear your experiences. When I try to explain it I get bewildered looks. People stop arguing with me but I think all I've done is inundated them into submission. As an engineer I get that a lot. What have you said and how did people react? Let's get some stories.
Have you ever seen a touch/tap to pay credit card? Those are hilariously easy to read without your knowledge. All it takes is a cell phone sized device, and you can walk around a mall skimming credit card information all day. This same thing would happen with an RFID implant.
That is not to say that the implant wouldn't be secure for a while, but it will be decrypted eventually and easily skimmed. An implanted device cannot be upgraded to handle new security standards as easily as a device not implanted.
Then again, we live in houses with glass windows and we all accept that pretty readily...so clearly most people aren't concerned with security.
As @ThomasEgi said, though, if people don't like something they will come up with whatever bullshit reason to hate it. People (particularly fundamentalists) made similar arguments against vaccines (it will rob us of our souls and turn us into cows), anaesthesia (suffering is God's will), and credit cards (the same mark of the beast stuff).
