According to emediawire.com, Internet Credit Card Processing requires more security and aggressive fraud controls than retail credit card processing because the credit card cannot be verified by swiping the credit card like with a retail merchant account. For this reason it's very important to deal with a company that specializes in internet transactions and Internet Merchant Accounts. An Internet Merchant Account does not require a shopper's signature and has requirements beyond a typical card-not-present or retail merchant account. Features that maintain security Prevent Duplicate Transactions - This feature tracks recent transactions to ensure the same transaction is not authorized more than once. This eliminates problems due to "double clicking" the transaction submit button as well as duplicate submittal of batch transactions. Transactions are tracked for duplicates over a one hour time period. Address Verification - Address Verification Service (AVS) matches the known address information associated with the given credit card number against the billing address information provided by the user. If the information does not match, the transaction is declined. The merchant has the option of choosing the level of match required for an approved transaction. The service only applies to credit card transactions. Negative Account Blocking - Enables a filter on account numbers. Transactions with account numbers on this list are declined. The Base level utilizes a database of negative account numbers maintained by this service provider. With the Merchant level, merchants can maintain their own list of negative account numbers. Account Number 3DES Encryption - This option allows you to enable triple DES (3DES) encryption of the account number when submitting transactions using the key. A 48 character key will be generated that you will be required to use to encrypt the account number with before submitting it to the gateway. Transactions received by the gateway via the API that were not encrypted with your key will be declined. Merchant Pin - The Merchant PIN acts as a private password that you can enable on transactions submitted through the API. This option helps ensure that only transactions submitted from you the merchant are processed on your account. Transactions that are submitted that don't have the correct Merchant PIN will be refused.
