NOTE: This module does not store card details on the shop. It uses TransArmor to manage credit card information. TransArmor allows you to have the 'card on file' feature. This means your customer can choose to pay with the previous card entered and not re-type the card info. Easier and faster checkout means more business to you! Even the administrator can use this feature to create orders via the Admin interface.
