More Examples of RFID Tags
I'm fascinated by RFID. I tend to be oblivious about technology - I love to use it, but don't ask me how it works. After our class discussion, I made connections that hadn't occurred to me when I was reading Little Brother. I was curious how we already use it. We mentioned Action Cards here at school. I talked to my dad and found out that he uses a card with one to access certain buildings at his work. The public library at home uses them to check out books. I used an Oyster card this summer. A scan through the Wikipedia page can give you an even longer list (including passports). Finally, I wondered if it was being used in cars. A quick Google search led me to this article: How thieves steal RFID-enabled cars. I laughed when I saw the byline.

The particular issue highlighted in that article is another potential pitfall with technology: backdoors. We don't often think of that, but often there is a way for some sort of "official" person to access stuff in the event of a failure of the more conventional means. Of course, it's often not difficult for anyone to find out these backdoors.
ReplyDeleteThere are also quite a few wallets and ID holders available that are made to block radio signals and keep your RFID equipped cards safe. Seems like the more advanced things get, the easier it is to take advantage of them.
