NFC tag keychain

Hello! This is my second model!

It's a read/write NFC keychain. You need to add a pause at layer 8 to add the NFC sticker.

I made this tag to fit a 25 mm sticker tag. Easily found on Amazon and they are very cheap!

I use this tag at work, i'm an EMT and this keychain can be scanned by any phone if we need a code to enter a building!

I could really use a Boost or a like!

I love feedback so don't hold back!
