DataLocker DL3 Secure Hard Drive

Typing on the DL3's backlit touchscreen keypad is easy, but you're also protected against "shoulder surfers" by a randomizer that shuffles the key layout after each use. What appears to be a normal keypad with sequential numbers one time will have a totally different order the next. And although the touch screen keypad offers no physical feedback, on-screen and audio acknowledgement of entries serve just as well.
