The fingerprint reader is recessed with a stainless steel plate and with a very small size of 81 x 37 mm (the thinnest of the market). It is mainly designed to be placed inside the door. As it is the same size as the Bluetooth reader and the touch pad, any of the 3 devices can be mounted in its slot. It is the smallest and finest fingerprint reader in the market and it is produced in Europe. The aluminum casing is an elegant feature of the design, suitable for any modern entrance door.
