When you have registered as a member online or in your studio, you will recieve an email with a username and password for Justface. Follow the link in the email, log in and upload a picture of yourself.
There is a tablet at the entrance to the studio, where you have to scan in via facial recognition. The result is held up against the image you have already uploaded in the system, and you will then gain access.
Should you have problems uploading your image, then you can always ask for help at your studio.
Justface is easy, and you will never have to think about membership cards or fines again, because you have
lost it.
