Payment Gateway

What is payment gateway?

A payment gateway is a separate service and acts as an intermediary between the merchants' shopping cart and all the financial networks involved with the transaction, including the customers' credit card issuer and your merchant account. It is like an EFTPOS terminal in cyberspace. It checks for validity, encrypts transaction details for security, ensures they are sent to the correct destination and then decrypts the responses which are sent back to the shopping cart.

FAQs

How will I know when I have an order?
When using a payment gateway system in connection with the cart, you will receive all of your orders via e-mail. As a merchant you will receive 2 e-mail messages, the first is generated by the cart, and supplies you with the necessary information to fulfill the order, such as names, addresses, and items ordered. The second will come from your payment gateway, and will tell you the status of the order approval. You should wait to ship a product until you have received this order status message.
