Today the word "bookmark" is probably applied to web browsers more than the little slots of card you'd use to keep your place in a novel, but it turns out you can bridge the gap through the magic of RFID tagging. That's what Instructables user talk2bruce did at TechShop, creating an Arduino-powered card reader that takes you to your favorite websites with a spiraling flourish of LEDs. Each RFID tag has its own unique number associated with a certain website, and placing it on top of the Arduino Internet Gizmo will open a new tab in your default browser. As you'll see from the video below, talk2bruce's top priorities include Twitter and the RadioShack website, but now he's got us thinking about which websites we'd like to render in cute little card form ourselves.
