Hello，About the operation step of how PN5321A3HN/C106 rewrite Sector 0 block 0 of UID card? Is there any relevant driver code?thanks！
I'm sorry for the inconvenience this might cause you but to write in that sector it's not available as the UID comes from the manufacturer and can't be changed.
If you want to identify in some ways the card, you can try to use the application storage.
