In a "Medical Emergency", how would tell those at your aid, vital information about yourself, that could possibly save your life.

How would you communicate with first responders if you were unconscious?

First responders and hospital staff can respond much quicker with first hand information regarding the casualty. An NFC tag can speed up the procedure.

A single tag can hold Information such as, an Emergency Contact number, Medication you are currently taking, Allergens and Anaphylaxis, Disabilities. anything that could potentially save your life or alert family or friends.

NFC [Near Field Communication] tags are small 25mm discs that store data. They are activated by simply tapping against NFC enabled devices.

The NFC disc requires no battery power. It is housed securely within the sealed compartment of the 3D printed holder. The holder which resembles a watch case is lightweight and is comfortable to wear.

These tags can also be password protected, to an Advanced Encryption Standard (AES-256) that the banking system uses.

The tag can also be set to allow a mobile phone to automatically call a pre-selected number for you.
