The U-Drive Memory Pen allows you to write your idea down on anything from wood to metal and then discard the writing. It memorizes what you wrote down and stores it on a flash drive. This frees you from having to carry paper or any other writing material around. Imagine being able to write someone’s phone number, address or other information down on paper and then throwing the paper away. This completely revolutionizes writing. Generally, the U-Drive Memory Pen looks like any other ordinary pen- it doesn’t require complex setup or components. To retrieve your writings, the pen needs to be connected to a computer via USB. The computer searches the inbuilt flash drive, finds your writings and allows you to edit, print and send it. But of course, the features comes at a price- its much larger than an ordinary pen and a bit awkward to carry around.
