 This PCB, as per the "PCB Hacker Card" tutorial, is like a business card but with one catch: it has NFC! The NFC chip on the card can be programmed to store a variety of things, from my email to a link to a website. This card is definitely not your average business card.

 ## Design
 While editing the PCB, I realized that the pads on the front of the board went all the way through to the other side, which didn't look good. So I did a bit of digging around the internet and figured out that I could use blind vias to have a trace on multiple layers without having an ugly hole in my PCB.
