Rohit Agarwal presented on biometrics technology, which uses biological traits like fingerprints, iris scans, and DNA to uniquely identify individuals. The process involves recording biometrics characteristics, converting them into images, encoding and comparing with samples, and storing as a future reference. There are two types of biometrics: behavioral (e.g. hand scanners) and physical (e.g. fingerprint, retina scanners). Biometrics are used for identification, attendance tracking, immigration purposes, generating ID cards, and provide security, safety, and time loss prevention benefits for businesses.
