Invisible Business Card's Details Are Only Revealed With a Glowing LED

You might think that an invisible business card is a terrible idea; how could anyone see your contact details? But artist Ghizlan el Glaoui’s card is a one-of-a-kind design that reveals all her important details with a glowing LED integrated into one corner.

Designed by a creative agency called The Big A, the acrylic card relies on a phenomenon known as total internal reflection which causes all of the laser-etched details to glow when the LED in the corner is squeezed and turned on.


Is it a card that Ghizlan would want to give away to everyone she meets? Definitely not—it’s almost certainly expensive to make. But when she needs to make a big impression, it’s a lot cooler than a tiny rectangle of card stock.
