Apple Card is a credit card developed by Apple Inc., designed primarily to be used with Apple Pay on Apple devices such as an iPhone or Apple Watch.
A preview was released to users who were invited to get Apple Card on August 6, 2019, and is scheduled to launch in the rest of the United States in the first half of August 2019. (Additional cardholders and joint accounts will not be supported at launch.)
Apple Card was announced at an Apple Special Event on March 25, 2019. Unlike previous special events which have historically served as platforms to announce upcoming hardware, this event focused on new internet software and services.
Other services announced at the event include Apple TV+, Apple News+, and Apple Arcade.
