Relates to fingerprinting or mandatory iris and retina scanning of employees

S 681 prohibits most private employers from requiring fingerprinting or mandatory iris/retina scans as a condition of hiring or continued employment. It directly affects private-sector workers and employers, with key exceptions for state/municipal employees, public hospitals, medical colleges affiliated with public hospitals, and private hospitals. The bill amends labor law to make this prohibition explicit and takes effect immediately upon enactment. It does not apply to government workers or healthcare facilities receiving public funding.
