COLUMBIA, S.C. (AP) — Families who use a supplemental program to help get healthy foods for pregnant women and children can now use the self-checkout at two national chain stores in South Carolina.

Health officials say Walmart and Kroger are now taking electronic cards for the state Women, Infant, and Children program at their terminals without cashiers.

The WIC program provides nutritious foods, education on healthy eating and breastfeeding and health service referral.

It serves 72,000 women, infants, and children up to age 5 in South Carolina.

Officials say they expect more retailers to sign on to allow the cards at self checkouts.
