You can easily transfer photos and videos from your phone to your electronic badge for display via Bluetooth through the app. Therefore, the APP will use your phone's Bluetooth function and need to access your photo album and call the camera function in order to transfer videos and photo albums to the electronic badge. But we will not upload your photos, videos, and other data to the server. The data will only be retained in your electronic bar and app. I hope our app and electronic badge can bring you a relaxed and enjoyable experience.
