Show HN: Stop typing numbers – scan and save contact info instantly

1•akash-bilung•2h ago
At events, meetups, or conferences, no one wants to stop and type phone numbers or emails.

That’s why I built a free tool to generate vCard QR codes — just scan and instantly save contact info to any smartphone.

It's perfect for business cards, booths, speaker slides, or networking tables. No app required. No signup. No tracking. Just fast contact sharing.

Try it here: https://contactconverter.app/tools/qr-generator

Would love feedback on the UX, edge cases, or features you'd like (batch generation, custom branding, etc.).
