Introduced in 2022 and conforming to the supply chain standard GS1, Walmart is apparently leading in adoption of 2D barcodes among retailers.  The 2D barcode is imprinted with thousands of digits that will incorporate sale-by date, available discounts and will allow stores to track inventory and to implement recalls.  Consumers who scan 2D barcodes will have information on nutritional content, allergens, promotions and food preparation.

Walmart is also evaluating AI voice applications to facilitate repeat orders and for customer convenience using online ordering and curbside pickup.
