Here are a few things to check:
1. Make sure that you are uploading a photo in a supported format. We support files that end in .jpeg, .jpg, and .png. If you have a different photo format you can convert it and then upload it. Most applications that handle photos will have an option to "save as" or "export to". You can use these to create a new supported photo. For security reasons we cannot support all file types for upload.
2. Try using a different browser. There is a known issue with uploading files in Firefox. This is not specific to Biometrica sites.
3. Check your photo quality. If you can upload a photo, but get a message that upload succeeded, but facial recognition failed to detect a face you may need a higher quality photo. Keep in mind that when you email or text photos they sometimes lose quality. This is because some services used for transferring photos try to save on the size of files by degrading quality a bit. While this is usually not detectable to the human eye it can make a difference in FR. Try getting the original photo file and see if that works.
4. Make sure that there is only one face in the photo you are uploading. This includes faces on t-shirts and photos or paintings in the background of the person you are attempting to upload.
5. Can you get a forward facing portrait of the person you are trying to upload? This is the type of photo most likely to be successful.
