I can't say I regularly tote around miniSD cards, but if this fun holder could carry a USB [0] stick, I'd be all for it. These card eating straps [1] which I saw on OhGizmo! [2] can be attached to cell phones [2] and cameras [2] so you know exactly where your memory card is at all times. Maybe not as bling as the Louis Vuitton charm [2] but much more practical and user-friendly than the cell phone cuffs [2]! Priced at $10. [2]
