Readable and writable electronic spell NFC card

 
Overview

Electronic Charms
    I saw that there are those kind of charm necklaces sold online. As a big friend who grew up watching "The Adventures of Jackie Chan", of course I really want it, but my pockets are empty, and it feels too heavy, making me look like a fool when I wear it. So here comes the electronic charm, inspired by the previous NFC card that was re-engraved by the big guy. It can read and write NFC, which is great as a pendant or necklace for friends.
Use electronic spells to defeat the mechanical Holy Lord. Heehee.
In the recent special period, everyone is afraid of turning into a sheep, so they wear a horse charm to protect themselves.
                                   A noble horse can eliminate all external forces.
Now I only draw tigers, dragons, snakes and horses. If you are interested, you can help draw together and collect the twelve talismans. (Hehe, save the Holy Lord)
The capacitor and resistor LEDs are both in 0402 package, and you can replace the 0603 package by yourself.
NFC chip model: NT3H1101W0FHKH
I use this NFC tool for nfc reading and writing software for ios. For Android, you can find NXP.
I hope that the horse charm that can cure all diseases can bless everyone and get through this special period smoothly.
  Monsters and monsters, leave now! ! !
