How is a person's identification verified?

Answer

Age-verification occurs through utilising a third-party trusted verification process that accesses existing robust data sources (credit card, driver's licence etc.). Age-verification companies do not hold the data - they request verification from existing sources to ascertain the age of the person requesting to be verified. A similar form of eID is currently being implemented in European countries and is intended to protect the privacy of the user. An adult-only site (whether that be for alcohol, gambling or pornography) is not privy to any information other than if the user has been age-verified or not.
