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: https://www.reddit.com/r/electronics/comments/efz9xf/my_nfc_powered_blinky_business_card/

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. 

  Are you sure? yes | no
