The "eID ‑ MitID age validation" app is an essential tool for businesses selling alcohol and tobacco products online, ensuring compliance with Danish law. By utilizing MitID verification, it efficiently checks the age of customers to prevent the sale of age-restricted items to minors. This app aligns with the June 2024 legislation passed by the Folketing that tightens the control over the sale of alcohol, tobacco, and nicotine to underage individuals. Failure to implement effective age verification systems can result in significant fines, with a minimum of 10,000 kr for alcohol and 25,000 kr for tobacco and nicotine products. The app not only complies with safety authority requirements but also saves customer age status at the time of purchase, offering streamlined protection for retailers. Additionally, it blocks transactions from customers who cannot be validated through MitID, ensuring only qualified buyers complete their purchases.
