When using the Cayan extension for your Magento store, you should tell your customers the following information:
Stored payment methods
When you enable vaulting, customers can add, or delete their payment information. If a customer wants to edit their payment information, they need to delete the stored payment information, and then add a new payment method during a transaction. Customers can delete their payment information using the Stored Payment Methods page.
Balance inquiry for gift cards
Using the shopping cart, customers can check the available amount of credit on their gift card using Check Available Amount.
Let us know if this answered your question. If not, please let us know why!
