README.mdInfo Card PCB
A pcb in the shape of a standard size credit card with nft reading/writing capabilities, contact information, and useful references on the back. It is fully designed in KiCad instead of EasyEDA with symbols/footprints sourced from Ultralibrarian.
Why I Made It
I wanted to take a notch down on all the highly complicated PCBs I've made and create something more artsy. I gained more experience from using Krita with its keybinds and workflow.
Schematic
It's really simple. I don't think you can run anything else from NFC but a few components.
BOM
It's the tariffs and shipping that got me. See more detail here on my efforts of trying to lower the price to fit the grant.

Questions
How big is the Info card PCB?
It measures 85.6 × 54 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Info card use?
31 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 Info card KiCad files?
From the udu3324/info-card repository on GitHub, at the commit this page was made from: the board is pcb/infocard/infocard.kicad_pcb and its schematic pcb/infocard/infocard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Info card design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
