Biometric technologies identify individuals based on their distinguishing physical and behavioural attributes, such as fingerprints, face, and voice. Unlike passwords or traditional identity documents, biometric attributes are inherently linked to a person and cannot usually be lost or forgotten, potentially providing greater security and convenience. This briefing focuses on how these technologies work, their applications, and the policy challenges raised by their use.

Fires at Grenfell Tower in 2017, Lakanal House in 2009, and other residential tower blocks have raised questions about how construction products affect the severity and spread of fires. This briefing considers how the fire safety of construction products is regulated; how products are tested and classified; and challenges for product testing and the building regulations more widely.
