The application will be easy to understand and navigate by all users. First the user must sign up and verify themselves, then update their profile with a latest photo and provide a payment method. Each user will have a unique QR code which they can use to scan at a scan station. The scan station will take a picture of that user and send it to the server for verification. If the verification is successful, they will receive a notification on their app. And the user will be awarded. The user can only claim once every 24 hours.
