Using our knowledge of NFC cards and data privacy, we created a product that eliminates this friction between digital business cards and paper business card users. Our NFC Business Cards had no initial market purpose, but as soon as we used it, people asked us how to get their own. Just like ourselves, the product has both a physical and a digital side: your Card and Website Profile. We built it to be as close as possible to the experience of offering paper business cards. As with using paper business cards, people using Only Card don't need an app to exchange contact information. .
