- Other people tend to give me business cards and they end up in an undifferentiated pile
- When people scan my QR code, the info goes into their contact, never to be seen again.
To address this, I created netcards. It's a dead simple PWA that I vibe coded with Claude. The workflow is as follows:
- Enter your info and an event name into the "My Card" page and save it. A QR code appears.
- Set up tags on the tags page
- When people scan the code with their phone's app, it goes right into their contacts black hole, but at least there's an event name there and all your info.
- If you scan app to app, you can select tags, which you can later filter on along with the event name.
- You can then share contacts, generate QR codes for them, or save the vcards for import into your native contacts app.
Obviously, the more people use this, the more useful it becomes, so I figured I'd start by sharing it with HN.
Tech: - Vanilla JavaScript, PWA with offline support
- IndexedDB for local persistence
- jsQR + qrcodejs for scanning/generation
- Bulma CSS, all dependencies from CDN

I've tested this on my Android phone only, so I'm particularly interested to hear from iPhone users about their experience. But in general, I'd like to know if people find this useful and if anyone has any suggestions.
