yeah but you would have to pump a pretty massive signal at it to be able to read it from a distance, or hav an insanely sensitive receiver

RFID's output is limited by it's circuit design. Someone with the right equipment could merely walk by you, or you by them, or a fixed location. It's a parasitically powered bloody radio transmitter, get it? We're not talking miles, we're talking feet.

Sure it's one big happy planet. Care to share your SS#?

Got me there! They can also be used to track your visits to any location that is properly equipped. The tracking cookie has jumped out of your CPU, and into your pocket. Not good.

You wouldn't think twice about someone in a business suit with a briefcase walking past you in an airport, or in a large office building, or taking the elevator down with you after a long day at work, or even a lawn-care guy walking past you carrying a leaf-blower on your way through the parking lot. But inside that briefcase or leaf-blower, could be an RFID reader, as well as a battery to power it. The backup batteries for most RFID systems are roughly 7"x4"x3", we all know how small the readers can be, and you wouldnt need anything too complex to record the small ammount of information read, hell, you could even fit a Sony VAIO laptop in a briefcase, as well as the reader and battery. That is if you couldnt just find a USB-Powered reader.
The point is, this person could walk right past you, or stand next to you in the elevator, then return to your work that night and gain access just as easily as you could the next morning.
I don't think anyone was talking about some guy with a wifi antenna on his roof stealing everyone in the city's RFID secrets. The main worry would be things like what I just described.

Thank you. It's that bad, and worse. It's possible, and probable to make much smaller rigs. The only thing that limits this is battery run time, and antenna size. Battery capacity and thereby run time can be sacrified to gain a much smaller profile. It needs only by powered up as the target passes by. The user could even use an existing RFID RF field to power up the RFID, then simply acquire it's information as it broadcasts it. A harmless looking person standing near one of many RFID scanners, a rouge security guard, etc.
Are you scared yet? You will be.

| | | | since these are radio transmission devices (parasitically powered as thay my be)could thay not be tailored in such a way that only a certain wave length could power them?
also could you not maybe find a way to encrypt this data? it is really just a mini radio transmitter after all. also as stated earlier RFIDs are usually used in conjunction with other forms of security due to the fact that thay could be easily red without ones knowledge and copied. it would be counter productive to put anything of great importance onto one such as a credit card number or bank information. and im pretty sure most of the industry knows that already. so no im not scared, your fear of such things is blown out of proportion

| | | | I just read the latest posts & yes it is scary the amount of info you can get without one knowing about it.....
That's whay I don't have any stuff like this.. Altho I'd like to find a way to disable the GPS on my cellphone....

Just the fact they can be used to track, and log your movement is bad enough. In reality an unshielded RFID is a radio transmitter freely beaming out any, and all information on it. Any code can, and will be crack, but many have little or no encryption.
There are people with broadband connection that still don't use firewall(s) for CPU's with sensitive data. Lack of vision, and failure to recognize security holes invites wholesale abuse.
