Your credit card donation will be processed based on the credit card payment option you select.
You have the option to select a Recurring or One time donation
If you select recurring, you can set the recurring frequency and the start date which will be when the donation is processed on your credit card.
If you select One time, you can then select "Give now" which means your card is processed immediately when you confirm your donation.
Or you can select "Give later" and select a future date.
Once your credit card is charged, your donation will be processed and sent to the charity in the next scheduled charity payout.
