YIKES! I hope I can rip out the RFID tagging.
RFID has nearly zero security measures as implemented today. You can get a slightly modified transciever and if close enough to grandma's rice sized chip in her arm you can read all her information. Just stand next to her for 15 seconds in line at the grocery and get the info
It can also be used to track a person - ala "Mr Davis, you went through the Holland Tunnel at 9pm, right after killing Mr Jones - your Toll transponder reported it" etc. We all know and understand this - geez its in all the technology news and they supposedly are addressing it.
Before I trust RFID to unlocking my home/car/etc without a key or keypad pin I want more security. Its already somewhat used in autos - BMW, Lexus, Honda and others have RFID tags embedded in the car key, it takes both a key and the tag to start the car. Lincoln Mercury has a tag with a keypad. Soem are already moving towards keyless/pad less "your car knows you" technology. Heck the Exxon transponders for paying for gas and items in the store are sent with low encryption - their only safety is that you have to be within 2-5 feet (or closer) to their transceiver. Thus I still use my cc or cash.
I see RFID war driving coming with boosted signals on modified transceivers.
Get out your aluminum foil hat people - they're coming after us! They will read your mind and wreck terrible horrible results on all of us! The old thought was we would all have barcode tattoos on our foreheads - now its rice sized capsules embedded in your forearm.
BTW Jerry, Honda demo'ed a riding lawn mower two years ago in their Ohio plant that started "securly" via handheld RFID tag - not embedded in your arm but I suppose it could have been.
PPS Mike I hate you!
You got me
You aren't too far off with this one though, they are, afterall, doing it in Japan already or a form of it.
Diatribe on RFID stands as written.
