Your digital badge is as good as your physical one. You can show it to a security guard or a Covid marshal. The advantage of the digital badge is that it dynamically shows, if you've done your Daily Health Check, have a valid and recent Covid test result and if your vaccination status is valid. It also displays if you are allowed to take pictures on set. Your badge contains your unique QR code that identifies you during testing or various other tasks where you might be required to check in. You can use both the physical and digital badge.
