RRcard is my NFC business card / hacker card. It uses an NT3H2111 NFC chip with a PCB antenna, so tapping it with a phone can open my links without needing a QR code or typing anything manually.
I made this because normal business cards are kinda boring, and I wanted something that felt more like a PCB project than paper with text on it. I also wanted an excuse to KiCad, fight NFC antenna math, and see if I could get a tiny board fab-ready.

Questions
How big is the Hackercard PCB?
It measures 86 × 54 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hackercard use?
11 parts, built around the NT3H2111W0FHKH. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Hackercard KiCad files?
From the RR-CREATOR/NFC-Card repository on GitHub, at the commit this page was made from: the board is PCB design files/hackercard.kicad_pcb and its schematic PCB design files/hackercard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hackercard design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
