NFC Energy Harvest PCB Business Card

I made myself a PCB business card with NFC tag that tranfers my contact info + powers an 8 bit MCU to blink two LEDs!

I made a PCB business card which powers a microcontroller using NFC. It also transmits my contact info over NFC! Runs an ST25DV64K for NFC and energy harvest, zener diode voltage regulator & an STM8L101F3 low power 8 bit MCU to toggle LEDs. Check out my original reddit post with a GIF showing it in action:

Ok, we're in 2023, but it's still cool. By the way, I have a business idea, but I am afraid of starting it. Fortunately, I found that made me think that I could do it. It offered me some information on this topic and I really appreciate the free essays on business I read on this source.

This is really cool. A bit of an overkill, but really cool.

Really cool project. How much power are you able to harvest with the current design? and is the project open source? I wanted to created something like this but with a twist it will save with the layout.
