When being deployed in an emergency, it is vital that the responders can quickly prove that they are capable of handling the situation, whatever it may be. When you arrive at the check-in station, you can use the Sigma Merits app to pull up your Sigma key, which will quickly allow an administrator to scan the key and view your Merits.
To access your Sigma Key, tap the icon in the center of the bottom menu to pull up a scannable QR code. This code is linked to your profile, and can be used by Orgs to verify your Merits and profile. The codes expire after 5 minutes. However, by tapping the refresh icon in the top right, you can instantly generate a new key for yourself. When your key is scanned, administrators can easily verify that you are certified and ready for deployment.
