Business Card with NFC Functionality and Silkscreened Text/Art
july 2026 • hardware • 4 min read
Below is the unedited journal I wrote for this project, which was submitted to Hack Club's current hardware YSWS: Forge.

My goal for this project is to complete it in one day (specifically, 3 hours). It's currently 5:09 PM, and by 5:30 I want to have all my tabs opened, so I'm ready to learn all the tools I'll need to actually create the card. I also want to set up a quick to-do list at the top of this journal, which I'll do now. The journal will use each task as a header. Turns out that each header reads as a different day in the website. Changed! (There will also be timestamps as each is completed, if the task is big enough to have an image associated with it.)

The above items were completed as a batch in this entry.

The tutorial has a yellow LED set up, but I want to find a white LED. Going to see if I can match the same electrical specifications but for a different colour.

5:39 PM
Did some research, and it turns out that white will never work due to the voltage. Furthermore, my backup (blue), will also never work due to the voltage.
bruh
Oh well, time to go back to the yellow.
5:52 PM: Wiring Completed

Pretty weird trying to get the red circles (connectors between wires) but that just shows my hardware knowledge after a 1 year hiatus :skull:
6:13 PM: Wiring Completed

Here's how I have my wiring set up. I want to have the physical raised portion of the NFC antenna serve as a box for some of my links. As I say this, I'm realizing I probably need to buy a domain for my website before actually having this card rendered.
6:38 PM: 3D routing complete
Wow was this more effort then I expected it to be. I cannot comprehend how crazy the art will be after this.
Decided not to add any extra functionality due to power restrictions with NFC.
Total time spent: 1 hour
7:11 PM: Importing dimensions into Canva
Used a converter to turn the JSON file into dimensions, and added them into this canva file.

8:34 PM: Updated tracing to fix for right-handed user
Took a bit of a break and came back to realize that since I'm right handed, the information and NFC reader would need to be on the left side for this to work properly. Fix completed.

9:03 PM: Added text portions
Added all the information I needed. Used the silkscreen and existing components as guidelines, with a trace being used to underline my name.

Total time spent: 2 hours
9:38 PM: Preliminary design completed
I've landed on this design, but it's still not perfect. the windows are a bit too sparse, the buildings don't come together well. furthermore, I don't want them to infringe on the NFC antenna.

10:10 PM: Front Artwork Complete
After a horrific amoutn of fiddling with x and y offsets and canva (scale was completely off, wahoo!)...

10:53 PM: Back Artwork Complete
After a few iterations (such as having the text be in the corners, rather than surrounding the compass rose), the back artwork is complete. A notable change is that the "big" on the left side is a bit expanded to match the silhouette on the "and" on the right side.

And with that,
