Cardnetics is a small, inventive brand focused on turning business cards into more than ordinary printed paper. Its products transform cards into toys, tools, gadgets, and playful promotional items, offering a memorable alternative to conventional business cards. The range includes assembled card creations and kits, with featured products such as the Penny Shooter, Small Iris Kit, Large Iris Kit, Small Iris, and Large Iris. The Cardapult is also shown among the bestsellers, though it is marked as discontinued.

Cardnetics shares experimental designs and provides free component drawings for people who want to build their own card-based creations. The site also features a video demonstrating some of the designs in action. The owner says the project will continue on a smaller scale alongside full-time work, with services reduced to make the business manageable. Custom printing is no longer offered, and restocking may be slower than before. Cardnetics is therefore best suited to curious customers seeking unusual card products or inspiration for hands-on projects.
