If the products you sell are restricted for a certain age group (products like alcohol, cigarettes, tobacco products, etc.) due to government regulations and you want to discourage visitors of that age group from browsing your website. You can do it by adding an age selection form to your storefront. With the implementation of this feature, you can use an optional date of the birth picker, use this feature globally or on a specific page or area, select the age limit (12, 18, 21, etc.), or cookies can be used with confirmed age that will expire after 14 days, and visitors might be asked to confirm their age again, this period can be modified as per your preference, a regular or a full-screen popup with a background image could also be implemented.
