Shock proof - duh, it's solid state. The worst you can do is crack the plastic shell.
X-ray proof - duh, it's not film. X-rays are not going to adversely affect electronic components.
Waterproof - Um, heat sealed (welded?) plastic packaging, I can see that. But only up to a meter; translation, weather proof. Add a bit of pressure and you can potentially cause the material or seal to crack. Appropriate material selection means that the contacts won't mind a bit of salt water, but make sure that you rinse the card before sticking into your camera.
