NFC CARDS
Near-field communication (NFC) business cards enable you to share your contact information with a single tap. NFC business cards have two components: a digital business card and an NFC tag.
NFC tags come in several forms, like stickers, pop sockets, keychains, and physical cards. They contain tiny microchips, and when tapped to another smartphone, the information paired with your tag (like the link to your business card) automatically appears.
