Kizunatap is a digital business card. You share it with an NFC tag or a QR code, the other person snaps a photo of their own paper business card, and you both end up with each other's contact. The other person does not need an app. Kizunatap works in the browser.- You can bring your own NFC tag. Any off-the-shelf tag works: write your card page link to it, and no special hardware is needed.
- The other person only photographs their own paper card.
- Claude Code and Codex can connect with an API key over MCP and API, and can manage your contacts. Anything that writes asks for confirmation first.
- Card pages and the landing page are available in Japanese and English. The admin screen is Japanese only.
Card pages and exchanges are free. Pro and Team plans are coming soon.
