I once had an aquapac for my camera, I wanted to see if I can fit the reader in it, but can't find it anywhere...
Anyway, with this
http://www.waterproofcases.net/ziplock.html I could take pictures underwater (aquarium

) so it'd be safe for teh reader too. Good thing: if it falls into water, it will float.
PS. the plastic is very clear if you chose the cameramodels (they're meant for taking pics underwater)
