Are Internet merchant accounts compatible with all shopping carts?
No. Shopping cart companies make their software compatible with certain secure payment gateways (ie. Authorize.net, Verisign, etc.) In addition, merchant account companies work with different secure payment gateways so their clients can process credit cards online. It’s important to take to find out from your merchant account company what secure payment gateway you’ll be using. If it’s Authorize.net, you can expect most shopping cart companies will support that gateway.
