Daily Cash with Apple Card

To use Apple Cash to make an Apple Card payment, see the “Pay with Apple Cash or a different bank account” section of: How to make Apple Card payments - Apple Support

or see the “Pay with your Daily Cash balance” section of Pay your Apple Card balance online - Apple Support

Just adding information to FoxFifth excellent post to verify the amount available.

Does the $500.95 appear in your Apple Cash card in your Wallet app on your iPhone? Look at the image below of my Apple Cash card amount circled in red. The amount shown on the Apple Cash card is the amount available for paying on Apple Card account. You cannot over draft Apple Cash.
