The credential schema lists the age assurance method – for instance, voice, facial scan, identity document scan and so on. And it contains other credential metadata such as an issuer identifier and expiration date. Legislation and discussion on age assurance has exploded globally, with major regulatory shifts ongoing in the U.S., UK, EU and elsewhere. Pornography, alcohol, cannabis, gambling, vapes, social media: just about all of society’s favorite age-restricted vices are being regulated, with their peddlers forced to ask customers to verify their age before transacting online. The methods for age assurance are nearly as varied, from document checks to biometric facial age estimation.
