The SWIPE Toolkit is a collection of web-based tools that sheds light on personal data collection and usage practices in the United States. The tools demonstrate the value of personal information on the open market and enable people to access information encoded on a driver's license or stored in some of the many commercial data warehouses.
Turbulence.org has sponsored the project which includes directions on how to decode the 2D barcode on the back of some drivers licenses, get information on what kind of data commercial warehouses are collecting and selling on you, and a data calculator, which gives you "the fair market value of your data bits."
Easy. Free. Disconcerting.
