It’s safe to say that microSD media is the smallest physical device which holds the most memory.  Just look around your house or office and think of all the things you could stuff a microSD card into.  Here we have a microSD card playing hide-and-seek inside a nickle.

Sure there is no technological advancement within this post, but it does remind you of the possibilities.

For the DIY folks out there, save yourself a boat load of money getting the right gear to slice a nickle and pony up the $30 to get the pre-fab’d microSD card inside a nickle at Spy-Coins.com.
