This is way too cool! I didn't even know they had a system like this using RFID.

I didn't end up reading everything about it, but a problem I could see is that the RFID getting copied. Didn't they have issues with this with passports and credit cards with RFID info on it? I think some people make a business out of selling RFID shields or something like that. I know that we have a likely possibility of getting our keys (with or without pushstart) copied, but I think I read that RFIDs are easier. Then again, you would have to know the person or follow them quite a bit to know they have something like this on their vehicle.

I'm not knocking the purchase or product; I really think this is such a great alternative to bring something that should be on all cars at an affordable price.
