The main purpose of age verification and user authentication services is to provide a means of confirming an individual user or an individual user's age over the web. Inova Suisse employs basic personal data such as the customer's name, address, phone number, date of birth (DOB) and the last 4 digits of the customer's Social Security Number, and ensures they match with the individual's personal data from various public sources. While the results are not guaranteed – it is possible for an individual to know someone else's birth date and Social Security Number – this service functions as a deterrent and is a commercially reasonable means of verifying age or ensuring the identification of a payor.
As detailed in the Inova Suisse Gateway Integration Specifications , the merchant can specify a minimum age for approving transactions, such that transactions that do not meet the minimum requirement are denied. Minimum age is set up for the overall merchant's account; it cannot be specified with each transaction.
