Do Digital Business Cards Actually Help You Get More Clients?

Hey everyone,
Quick question I’ve been thinking about...
I’ve seen more people moving toward paperless networking — QR codes, digital cards, NFC taps, etc. I’m curious if anyone here has used a digital business card and seen results from it?
I recently built a tool (called 2TalkLink) to make it easier for freelancers and small businesses to share their info without printed cards. It works with QR codes or links and can be shown directly on your phone during client meetings, events, or even cold outreach.

But here’s what I want to know:

• Have you ever landed a lead or sale just by sharing a digital card?
• Do you think it’s worth using if you already have a website or social profile?
• Any creative ways you’ve used it for offline-to-online conversion?

Would love to hear real feedback or ideas — I’m still improving the tool and figuring out how people are using this in the real world.
Appreciate your input!
