README
README.mdNFC Cards
So, I’ve been messing around with NFC tech lately. This repo is basically the home for my NFC business card project. I wanted to make something cooler than a piece of paper, so I designed a custom PCB that doubles as a digital business card using the NT3H1101 chip.

How to make your own
- Clone the repository (or download the kicad folder). Open it. Modify the silkscreen to your likings. I used Canva. Then export gerber files. And Get it manufactured (JLCPCB.PCBWAY,etc)
- Dont forget to post yours online!

Questions
How big is the 12. PCB Business Card PCB?
It measures 89 × 50.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 12. PCB Business Card use?
10 parts. 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 12. PCB Business Card KiCad files?
From the DevX-Dragon/NFC-Cards repository on GitHub, at the commit this page was made from: the board is KiCad Files/12. PCB Business Card.kicad_pcb and its schematic KiCad Files/12. PCB Business Card.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 12. PCB Business Card design in my own project?
Its repository states no licence, so its author keeps all rights: ask DevX-Dragon before reusing the design.
