IRIS IRISPen Express 7 Pen Scanner
Although this might not be the overall best pen scanner on the market, it's a great option if you're looking for a pen scanner on a budget. It can recognize over 40 languages including English, French, German, and Arabic, as well as including both text and numbers. While this one only supports Windows operating systems, it has full integration with a wide range of applications such as Word and Excel. It's easy to use and is powered through the USB connection that transfers data from the scanner to your computer. The lightweight design means you can use it comfortably for long periods of time, and the scanner can recognize barcodes and even scan small images. Although you don't get a lot of bells and whistles with this one (such as an online dictionary or Bluetooth connectivity) it's an affordable option that works very well with PCs running Windows.
