From here, they can pay using any of the credit cards that you have enabled as part of your payment settings (see below).
After the payment is processed, the visitor is returned to the Invoices and payments tab on their member profile, where an invoice will appear, along with a payment entry, if the payment was successful.
For security reasons, credit card information is not stored in Wild Apricot. Instead, it is securely transmitted to AffiniPay where it is processed. AffiniPay then returns the status of the payment transaction, which is recorded in your Wild Apricot transaction details.
