Age verification is a process used to confirm a person's age, typically to ensure compliance with laws and regulations regarding age-restricted products or services. This is commonly seen in industries like alcohol sales, online gaming, and adult content websites, where access is limited to individuals above a certain age, often 18 or 21 years old. Methods of age verification can include checking government-issued identification, using online verification services, or requiring users to input their birthdate. The goal is to prevent underage access and protect minors from potentially harmful content or products, while also ensuring businesses adhere to legal requirements.
