A barcode reader and a barcode reading system having an age verification capability are disclosed. The barcode reader may capture a barcode pattern on an identification (ID) card of an individual presented within a field of view of the barcode reader, extract date of birth information from the barcode, and verify an age of the individual. The barcode reader may provide an approve signal if it is verified that the age of the individual is greater than a high threshold or a deny signal if it is verified that the age is less than a low threshold. The low threshold is distinct from the high threshold. The age may be verified by a host computer. The barcode reader may extract a product ID and send the product ID to the host computer. The host computer may then prompt age verification operation if the product is an age-restricted product.
