Viz-card, a smart business card

People often demo products or meet a large group of people where the audience may need to know about their background, credentials etc. Conventionally people exchange business cards to communicate who they are. This hardware device strives to provide a smart business card experience. Built using an Arduino microcontroller, LED lights, a display screen, and an accelerometer, Viz-card tells pre-feeded information about the author as users interact with the device. As users lift the device, rotate it, the display screen shows new information.
