This type of bracket is mainly used for face authentication devices and iris recognition devices. Because this bracket enables you to adjust a device's angle by tilting it, it can minimize the movement required by users to come within the authentication-capable range. It also allows users to authenticate themselves with ease, regardless of their height or wheelchair use.
