LOOPID LINK
Ditch paper business cards — share contacts with a tap.
LOOPID turns your business card into a QR code or NFC tag. Share your contact info with a single tap or scan — no app needed for the person receiving it. Privacy-first: you decide exactly which details each person sees, and create different cards for work, personal, or events.
Hey Product Hunt 👋
I'm a solo dev, and LOOPID.LINK started from a small, embarrassing moment: I showed up to an event and realized I had no business card. So I hacked together a quick app that shows my contact info as a QR code.
It… didn't go great. Asking someone to scan your phone the second you meet them is awkward, and I went home with a stack of paper cards I'd already forgotten the context for.
So I kept building. LOOPID now lets you:
Share your details via QR code or a single NFC tap (write your profile link to Loopid.link to any NFC tag)
Let the other person save your info with no app required on their side
Control exactly which fields each person sees — privacy-first by design
Keep separate cards for different contexts (work, personal, an event)
It's free to try, on iOS, Android, and web.
I'm still figuring out the hardest part — getting it in front of people — so I'd love your honest feedback. What would make you reach for something like this instead of paper (or instead of just texting your number)? And for the NFC crowd: do you already tap-to-share, or is it still niche?
I'm building this in public and I'll be here all day to answer anything. 🙏
