Memory card readers come in all shapes and sizes these days, but few rely on a rechargeable lithium battery to power their . . . built-in cash note verifiers. Yes, this innocent-looking ladybug 3-in-1 reader ($16) is absolutely unforgiving against counterfeit currency. Don't ask me how it works (I couldn't tell you if you did), but the 2.2" x 1.4" x 1.0" ladybug is packing a black light (?) somewhere under those wings that "illuminates" the security strip embedded into U.S. dollars.

If you've never questioned the legitimacy of the cash in your wallet, you can still make use of the ladybug's integrated USB charging cable and ability to read T-Flash, microSD, and microSDHC cards.
