Biometrics refers to physiological characteristics that can be used to identify people ranging from fingerprints, to retina recognition, and from speech recognition to electro-physiologic characteristics such as heart or brain waves. Employers have begun to use biometric characteristics to identify employees and control access to premises, computer systems and even vehicles. Employees who object to the use of their biometric data have begun to bring claims based on a variety of legal theories, and some states have passed legislation limiting employers in their ability to capture and use such data. This CLE session will address: (1) what are biometrics; (2) how are they being used in the workplace; (3) what types of claims have employees been able to assert; and (4) what statutory claims are emerging.
