In performing any of the social worker's duties, the social worker shall display the identification card and such card shall be accepted as proof of the social worker's identity unless the person to whom it is displayed has a good faith basis for denying its authenticity.

(d) No person, facility, school or law enforcement agency, jail or house of correction shall require a social worker employed by the department of children and families to provide, in connection with the performance of the social worker's duties: (i) documentation including, but not limited to, a driver's license, other than the state-issued identification card described in subsection (c); or (ii) the social worker's home address or personal telephone number.
