CIRCLean is a USB key sanitizer which helps you to avoid malware infections.
Malware regularly use USB sticks to infect victims and the abuse of USB sticks is a common vector of infection (as an example Lost USB keys have 66% chance of malware).
CIRCLean is a independent hardware solution to clean documents from untrusted (obtained) USB keys / USB sticks. The device converts automatically untrusted documents into a readable format and stores these clean files on a trusted (user owned) USB key/stick.
