NFC is a specialized radio frequency protocol designed for very short-distance communication. It allows two gadgets to "talk" to one another simply by tapping them together or bringing them within an inch of each other, making it the primary technology for secure mobile payments and digital keycards.

Think of Cardyn as your last business card. It is a high-tech smart card equipped with an embedded NFC chip. Instead of handing out a paper card that might get lost or thrown away, you simply tap your Caedyn card against a smartphone to instantly share your digital profile, contact details, and social media links.

If you meet someone with an older device, they can simply scan the code with their camera to instantly view your profile.
