Cardio is a digital card built for the way we connect today—clean, fast, and always on. No apps, no printing, just one smart link or scan that shares your professional details in seconds.

👋 Hey Product Hunt! Clement here!
I’m usually the data guy who working behind the scenes, but today I’m stepping out to share something I built with my partner, @cindyaffandi (she’s the design brain and I’m the code guy)
Cardio started with a problem that felt small, but kept coming up:
You meet someone cool, have a great conversation... and a few days later, they forget who you are. You gave them your number, maybe even a card, but it didn't stick.
So we built Cardio: a simple, clean way to make sure you're the one they remember.
It lets you share everything about you in one smart link or QR code, your name, role, socials, contact info, and anything else you want to be known for.
Here’s what it does:
✅ Instantly saves your contact into someone’s phone (no app needed)
✏️ Edit your info anytime, it updates automatically
🔗 One smart link or QR with all your details
No downloads, no apps. Just one clean, modern way to help people remember you.
We've seen people use it at events, in interviews, pitches, even on their resumes and email signatures. It's been incredible to see it actually work.
If you’ve ever had someone forget your name 5 minutes after meeting... or wondered if they ever followed up because they couldn't find your info again... Cardio is for you.
Would love to hear what you think. Thanks for reading 💛

Just out of curiosity – why did you opt for "Cardio" naming?
Because when I first saw this, I thought it was a fitness app.

@busmark_w_nika Haha fair question! We get that a lot 😅
We went with Cardio because it felt like a fun twist on “card”
It’s not just a static name card, it’s digital, always with you, and helps keep your connections going. So in a way… cardio for your network 💛
This seems like a very good idea! Can users also add multimedia and/or custom branding? Is there support for NFC tags as well?

Hi @pranay12 thanks so much for the kind words! 😊
Right now, users can customize their Cardio with images, a banner, and brand colors to match their identity. We don’t support other media types yet, but it’s definitely on our roadmap. If you have specific assets you’d like to include, feel free to let us know. We’d love to hear your ideas and see if we can incorporate them in an upcoming release!
As for NFC, we don’t have plans to support physical NFC tags at the moment, as we’re focusing on keeping Cardio a digital-first product. But we’re always listening, and we appreciate your feedback. Thank you!
