Not yet I wouldn't. Seems like it wouldn't be too hard to create a portable reader that would grab data off of other people's chips without their knowledge - when you shook hands with them, maybe. Once you've got the data, it couldn't be too hard to duplicate the operation of the chip, and hey, you're in someone else's house/car/computer/etc. That's my biggest concern. If it's taken care of, yeah, I'd consider it.
