An NFC (Near Field Communication) digital business card is a modern, tech-savvy alternative to traditional paper business cards. Using NFC technology, these digital cards allow users to share their contact information, websites, social media profiles, and other details with a simple tap on a smartphone. NFC digital cards can be stored and accessed through mobile apps or QR codes, offering a sustainable and easily updateable solution for networking. They also eliminate the need for physical cards, reducing waste and providing a more eco-friendly way to exchange professional information.
