Illinois’ Biometric Information Privacy Act (“BIPA”) is considered the most comprehensive law governing the processing of biometric data. Passed in 2008, BIPA sets out requirements for private entities, including employers, that collect, use, store, and share biometric information.  It’s also one of the most popular class action suits today – hundreds, if not thousands of cases have been filed in recent years – and there is no sign that the litigation is slowing down.
