Thumb drives are great, because they’re so pocketable, but what if you want to be a little more discrete? OCZ has you covered with their latest flash drive: the Mega-Kart has the same footprint as your American Express but instead of putting you in debt, it’ll store up to 8 gigs of invaluable data.

The Mega-Kart measures 85mm by 54mm, but is quite a bit thicker than a credit card at 3.5mm of girth. That’s okay though, because it comes with an integrated USB connector and is compatible with USB 2.0. Naturally, it’s a plug-and-player with Windows 98, 98 SE, ME, 2000, and XP, but it can make friends with OS X and Linux Kernel 2.4+ environments too.
