A digital business card is a shareable link or app-based profile containing your contact details, often with social links, a photo, and a "save contact" button — sent by text, email, QR code or a tap.
It's a natural fit for remote-first professionals and anyone whose networking happens mostly over video calls or online, where a physical card doesn't get exchanged in the first place. Details update instantly with no reprinting cost, which is its main advantage over a paper card.
Digital cards don't fully replace physical ones where in-person trust-building still matters — many professionals now reasonably use both, depending on the setting.
