Membership Vault (MVault) is a membership registry system enabling stations to easily provide conditional access to premium PBS digital features. It allows stations to manage the relationships between its members and online offers and is designed to be the gatekeeper for online digital services. Stations can determine thumbs-up or thumbs-down access per member for every digital service. For example, a service like membership video on demand (Passport) will query MVault to determine if a viewer is allowed access. Future digital services will do the same, making it easy for stations to adopt new offerings without additional work. In addition, new online users who are interested in your station are also recorded in MVault allowing you to gather new prospective members for development purposes.
