I was thinking a fingerprint scanner is exactly what's missing on these devices (what I've seen so far, Coin, Echo & Wallaby), but this is also an interesting solution with iCache.
Too bad about what happened to it. (Actually just found out about iCache and what exactly happened and while I'm sad, I can't say I'm surprised.)
