Existing law restricts the sale of certain products to customers 21 years of age or older. These laws generally require proof of age by checking a valid identification card of the customer at the point of sale. This bill would require retailers of alcoholic beverages, tobacco or vape products, or consumable hemp products, after a violation for failure to verify a customer's age, to use a digital system or card swipe technology to verify the age of the customer at the point of sale. This bill would authorize any retailer selling an age-restricted product to use these age-verification technologies.
