When you open the mobile app and are set to initiate your first gift card activation, you will be prompted to enter your payment method. We accept all major credit/debit cards and also on Apple devices, we are adding ApplePay support. The billing address for your credit/debit cad must match the location where the Starter Box or Starter Pack was shipped, to help us manage the ownership and inventory restrictions on the cards. If you need any assistance with this, please submit a support request via the Help "?" Button on the CardNow Support Center page, or email us at Support@CardNow.com.
