At least once each calendar month, the Department of Human Services shall cross-reference its roster of public aid recipients with the death records information from the Department of Public Health residing on the Electronic Data Warehouse at the Department of Healthcare and Family Services. A public aid recipient who is found to have a death record shall be subject to an immediate cancelation of his or her public aid benefits, including the deactivation of his or her LINK card, in instances where there are no other individuals receiving benefits in that assistance unit and upon certification that the identity of the public aid recipient matches the identity of the person named in the death certificate. As used in this Section, "LINK card" means the electronic benefits transfer card issued by the Department of Human Services for the purpose of enabling a user of the card to obtain Supplemental Nutrition Assistance Program (SNAP) benefits or cash.
