A payment gateway is an e-commerce application service that authorizes payments for online retailers. It is the same as a card swiper at a brick and mortar retail store. A payment gateway protects credit card details by encrypting sensitive information, such as credit card numbers, to ensure that information passes securely on the web.

Here are the Merchant Account and gateways that we recommend:

gateway-authorizenetAuthorize Net
This is the defacto standard for online transactions. Most all shopping carts have Authorize Net setup as a gateway. You can also signup for a merchant account through Authorize Net.
gateway-paypalPaypal
This service is an all-in-one merchant and gateway service. You can start with a free account as well as subscribe to a virtual terminal.
