Lots of people have a token with the likeness of St. Christopher, the protector of travelers, in their car. When we bought a car, we got one from klik's parents. It lies in the space under the car stereo.
So, why not entrust the precious data on your USB memory stick to the Virgin Mary?
I quite like how the likeness of the saint is the thing that needs to be protected. That must count for double points!
