Apple Card Family
Apple announced this feature during its May event, but it wasn’t until now that you can share your Apple Card with other members of your family.
Now you can officially share your Apple Card with up to five other people, including people from your Family Sharing group. Keep in mind, though, any member that shares your Apple Card needs to be at least 13 years old.
Additionally, you can track all expenses made with Apple Card, as well as managing and limiting spending for any member of the family. And probably the best reason to use it, other people you share your Apple Card with will also be able to build up their credit score with you.
