Google introduced the Family library, which allows you to share content in Google Play from among the six members of the family. Buying an app, game or movie, the user can completely free to provide access to their relatives.
After authorization, new content will appear there automatically (you can disable this option in settings), and if the user does not want to share some content, he can add or remove individual purchase.
Adjusting the settings of the Family library, the user can select one credit card, so-called "shared payment method" by which his family will be able to purchase content. If desired, they can use their own maps. When someone made a purchase from a joint account, then its owner will receive a receipt by email. If the family has children aged 13 to 17 years old, he can approve or deny the registration of their order.
