Apple provides additional details regarding the Apple Card Family features and restrictions

According to Apple Insider, the details are available in a support document and reveal that Apple Card Family is available to one cardholder and one member of their Family Sharing group who is 18 or older. Therefore, the product enables both members of an account to share a credit line while simultaneously building credit. A total of six people, including owners or co-owners, can be assigned to a particular Apple Card account, while participants must be 13 or older.

Moreover, co-owners share full responsibility for account balance and payments, and have their credit reported equally in their own name. Once assigned to an account, a co-owner is eligible for Daily Cash back on purchases, which can range from 1% to 3%, depending on payment method and merchant. Additionally, owners and co-owners are enabled to do the following:

• add or remove participants and order a titanium Apple Card for participants who are 18 years or older;

• view participant activity and account co-owner activity;

• set transaction limits for participants, lock a participant's ability to spend, and receive notifications on participants spending;request a credit limit increase;

• close the shared Apple Card account at any time – although they are still responsible for paying any remaining balance.

Furthermore, Apple Card holders who want to use the new family feature need to set up Family Sharing or be part of a Family Sharing group. Additionally, using a device that has its region set to the US, enables owners to invite family members to an account in the Wallet app. Apple Card Family is expected to arrive in May 2021.
