A floating case has a rigid layer and an alternate joined buoyant layer. The rigid layer has at least one chamber for a larger memory card and at least one minor chamber for a smaller memory card. Each chamber has first tabs, second tabs, and a tongue that secure a memory card. The buoyant layer displaces water so that the device floats and preferably has the rigid layer floating above the water. The device and its layers have a left end, a right end, a front, a back, a top surface, a bottom surface, a first corner and at least one second corner. The rigid layer and the buoyant layer have a waterproof construction and the buoyant layer has a light weight to volume ratio. In an alternate embodiment, the device has a hole through its top surface and the bottom surface for a lanyard.
