I just finished watching "I, Robot" for the third time. No, not in a row. First time was in the theater when it was released, second time was on DVD at a friends house a couple of years back. I've been thinking about how tech in movies is catching up with physical reality.
The prop above is from that movie. A detective's ID. The way it works is you simply show it to whatever scanner you're in front of. The robots know who he is from that ID. So today, you now have RFID and Bluetooth. Most of the current ID tech relies on the same concept. All we need is auto-pilot cars with spherical wheels. The robots are here. Just not in people's homes. Yet.
Anyway, RFID and Bluetooth are those types of tech that are scary good. The good news is anyone can find you. The bad news is anyone can find you.
Please, people, be VERY sure of what info you have on the internet. How public do you really want to be? If you value any kind of privacy, keep your cards at home, and your phone with Bluetooth disabled.
Of course, going with the trends, RFID is eventually going to be embedded in driver's licences and state ID cards. Consider keeping those in the glove compartment. Because your car is going to want to know who you are for auto locking mechanisms, you might want to consider installing old-style key locks. And nothing with a card. A good old fashioned metal key.
And this advice is coming from someone who advocates RFID/Bluetooth/WiFi soda machines. I feel like such a whore.....
