There've been a great many memorable business cards made, but few can rival this one for sheer hi-tech usefulness.
The SwivelCard features a built-in USB drive that folds out and, when plugged into a computer, directs the user to a website where you can host extra information about yourself - which you can remotely update as and when required. Each one contains a unique ID, enabling you to find out who has and hasn't 'checked in', and the analytics from their visit.
The SwivelCards are available to preorder through an already-funded Kickstarter, created by Washington-based engineer Andrew DePaula's company Spokane: it's already received five times its original target of $10,000 (£5,950). $29 (£17) gets you 10 SwivelCards, with $79 (£47) getting 40; bigger, cheaper packages are also available if you're happy to splash the cash. Shipping is expected in November.
