There is software available to entirely remove the data from removable media. The exact procedure will depend on how the pen is connected and how it appears to the computer, but it is possible. Running this process before the fieldworker leaves the house should solve the problem.

Subject: [data-protection] Portable Scanning
A growing number of our fieldworkers are using portable scanning to increase efficiency and effectiveness. e.g. they may scan personal documents at a clients home to avoid an office appointemnt or use of post, which causes delay and /or has other risks.
They are typically using pen type devices, which work well in practice. Image is then transferred to a (very secure !) laptop before later upload to main systems.
The scanning devices are however not encrypted. We have not been able to identify workable encrypted alternatives at the present time - too slow, too prone to crash or simply unreliable. They are wiped after transfer before leaving the scanning location. There is a theoretical risk however that if lost, although apprently empty, with the right tools an expert could retrieve most recent images.
Has anyone come across this issue and found a risk free solution ? Or does anyone accept such a risk on the basis that e.g. safer to lose an apparently blank device with a few fairly low level personal documents rather than a briefcase full of originals / photocopies.
