Open house does not mean the whole house is open. Whether it concerns an exhibition in the foyer of a company, or sensitive rooms such as operating rooms in a clinic, server rooms, machine rooms, laboratories, treasuries of all kinds or other restricted zones – when it comes to visitor control or access management a biometric solution surpasses everything. In a museum, for example, a biometric fuse reliably indicates whether someone is getting to close to a work of art, or whether it is only being cleaned by a trusted person authorized to do so.
