 Shoppers can get all kinds of things from vending machines, food technology, and now bullets. In convenience stores in Alabama, Oklahoma, and here in Texas, a company called American Rounds has installed vending machines that dispense ammunition, but only after the purchaser scans a valid ID into the device. Then it's going to do a facial recognition to match that person's face to the picture on the ID. Company founder Grant Major says it's more reliable than online ammo purchases, which also are legal.
