Despite his small size, everyone's favourite Astromech droid has saved the day more than once, and proved himself to be a brave and loveable hero in the process. So what better way for a Jedi in training to conceal his valuable items than hiding them away inside Artoo himself?
The R2D2 Smartsafe is only unlockable through a combination of your specific smart phone and a 4-digit pin combination. No lightsaber, mind tricks or loosening his restraining bolt will get you inside this "very well-put-together little droid". But as long as you've downloaded the app, you need only to dock your phone, tap in your code and the R2D2 lockbox will reveal the secrets within.
