Medical Alert NFC keyring

This compact key-chain contains an NFC chip that securely stores your critical medical and emergency contact information, allergies and health conditions. with a simple tap from any NFC enabled smartphone, first responders or good Samaritans can instantly access the details that matter most - helping sale valuable time when every second counts.

I used NGAT215 NFC stickers from Amazon, vcard-go.com to create the virtual card and Seritag to write to the NFC. V-Card-go and Seritag are free programs. You can also use the NFC Tools app, but iPhones cannot read a text only file, which is the reason for the VCard-go as it creates a virtual contact card. Add whatever information you need and you can lock the NFC tag so it can't be written over or modified without a password. This allows you to modify or update the information as necessary.

The file has the pause built in, but if for some reason you need to add the pause, it's at layer 11. The pictures and the file setup are for reference only. The tag should be printed with the cross symbol face down and the text face up. 

Figuring the key-chain would take a beating, I used a .2 layer height, 3 walls, 50% gyroid infill, 5 bottom layers and 5 top layers, 4.0 nozzle. I used a .4 nozzle, but a .2 nozzle would give a better finish to the symbol and text.
