_**DESCRIPTION:**_ This keychain sized nfc card made by me is meant for new techies (maybe you?) to realize how cool and interesting PCBs are!
_**WHY I MADE THIS:**_ When I first showed off my onboard personal NFC card, everyone was asking, 'What does that do? What does this do?'. So I made this so they can find it out on their own.
_**TOTAL TIME SPEND:**_ 1 hours
