How It Works

  1. Choose Your Mode: Decide between creating an online profile or generating a serverless QR code that contains your medical information directly within the code.
  2. Create Your Profile: If opting for an online profile, enter your essential medical information into our secure platform.
  3. Generate QR Code: OpenTag creates a unique QR code linked to your online profile or encodes your information directly into the QR code for the serverless option.
  4. Apply the Tag: Print and attach the QR code to personal items like helmets, backpacks, or vehicles.
  5. Emergency Access: In case of an emergency, first responders can scan the QR code to access your vital information instantly.

Flexible Options

OpenTag offers flexibility to suit your preferences:

  • Online Profile: Maintain an online profile that can be updated anytime, with the QR code linking to the most current information.
  • Serverless QR Code: For those who prefer not to have an online profile, OpenTag can generate a QR code that directly contains your medical information, ensuring complete data sovereignty.
