SIM (Simple Integration Method) is a secure online payment-processing system for the shopping cart that allows Internet-based businesses to authorize, process and manage credit card transactions directly from their Web site. There are no worries about the complicated software, hardware and expertise normally associated with enabling e-commerce.

The integration method captures the necessary customer information (name, credit card number, etc.) from a merchant’s own secure transaction page, or it can display a customizable transaction page hosted on an Authorize.Net secure server, for the customer to fill out.

The customer’s information is encrypted using 40- or 128-bit Secure Socket Layer technology and sent from the shopping cart to an Authorize.Net transaction server. The server sends the data through the authorization network to the appropriate card issuer's bank, using a secure, proprietary connection. When the authorization process is complete -- this takes around five seconds -- the customer receives an approval or decline response and the Authorize.Net server stores the transaction. Transactions are automatically settled each day and are funded within two to three business days.

We also have an alternative payment solution for the SIM payment method. Merchants can check the status of transactions or run reports on past activity by going to the Authorize.Net Web site and logging on to their own password-protected Authorize.Net site. And online businesses can use the Authorize.Net Virtual Terminal to enter payment information manually if customers prefer to call in their credit card information.
