      Hmm... Roger seems to have a trend of recommendations against protecting yourself. In the case of the RFID wallet, he makes total sense. I've never even though of buying an RFID blocking device.

      But someone on SW thinks that firewalls are useless because of this nonsensical piece of crap article: http://www.infoworld.com/article/2616931/firewall-software/why-you-don-t-need-a-firewall.html

        Easily one of the creepier RFID things I've seen

            Another RFID issue that I've seen is schools forcing children to wear RFID tags. It sounds great that during the school day the school knows what room they are in. That's fine. The problem is that when kids walk home creepers can stalk them without being visible to the kids themselves. A potential abductor can lurk behind a fend, use a simple scanner to tell when the children have separated from a group, identify their exact location and abduct them knowing that the school has ensured that he (or she) has identified a child within a certain age bracket, their location and the potential location of friends who would miss them shortly.

            Talk about someone working hard to put kids at severe risk!

                The range of RFID is really short (centimetres). Essentially you'd see the kids long long long long long before you got an RFID blip.

                  Battery powered ones have a range of about 300 feet.

                    But RFID? yeah your passport is the only thing I can think of that most people have with one in it.

                    Yeah, I hate that one. It makes American children identifiable when abroad from a distance. You don't need to be able to read the RFID, only see it. It becomes a tracking device (over very short distance.) But the scariest thing is that if a family is all carrying their RFID passports as they are told to do, someone in a crowded marketplace or other public area can use them to identify foreign children and, more scarily, identify when they have become isolated or are out of line of site with their accompanying adults.

                    As someone who lives in a tourist centered city, I PROMISE you that we know you're tourists from a block away. Sometimes more.

                    Edit for obligatory joke: Why do they bother to call it tourist season? You're not allowed to shoot them.

                      @johnhooks Doesn't EZPass (or any of the toll system) basically use the same tech with power-less devices and powered readers?

                        I believe so.

                          A lot of stores use them to track inventory on the floor also.

                            I've seen that at Best Buy and the B&N on RIT's campus had those on most of the books. I think one of the professors (or maybe B&N) were trying to do an instant tally/checkout implementation.

                              when we were in Africa we actually all carried copies of our passport and Visa's. Were told when we were in the capital city to keep our passports tucked away in blocking covers so that they couldn't be tracked easily. We were white, easy enough to spot as it was, and prime targets so don't give them any extra information.

                                Oh now, it is very long. Even in the 1990s the VNC team at Cambridge could be tracked anywhere in the building with them. I know the ones in our car go like a hundred feet or more. I know that grocery stores have them that go ten feet or more.

                                  Yes, and they get some huge distance. And that's the distance at which you can READ it reliably. You can IDENTIFY one from many times that distance.

                                    German grocery stores have been doing that for over a decade. NTG was looking at stuff like that in the early 2000s to replace our medical bar coding systems.

                                      Alright if they've got "active" (battery powered) stuff and they call it RFID that's a lot different than passive (chip only).

                                      Passive / chip only stuff is at best a meter or two (with a huge antenna like grocery store exits) - typically less than 10cm for stuff like bank cards, passports, etc.

                                      Note: I don't think it's "RFID" anymore if you put a battery on it. Then it's just a bloody radio lol. And fair play I suppose, "Radio Frequency IDentification" but really the whole thing was supposed to be a passive reflector that lit up a specific frequency when pulsed by an antenna.

                                        No, EZPass is not a powerless system. they have batteries. That is how they get the range they get.

                                        Powerless RFID is very short distance. The theoretical max range is only 5 meters to begin with under perfect conditions.

                                          @JaredBusch there is a battery in the units that the customer takes with them in the car?

                                          I've never seen where those units come apart to provide a new battery.

                                            They don't. You have to replace them.
