When we speak about security for credit card processing, we need to understand that one of the first and foremost things is to ensure that the information that passes between the merchant’s website and that of the payment gateway is secure at all times. To ensure this, all websites use a security encryption system. The standard is 128 bit. This security encryption system encrypts the information packets that originate at the merchant’s website and reach the payment gateway. At the same time the payment gateway also uses a separate security system that ensures that the information is processed in a secure environment that is hack proof. The information through the secured connection back to the merchant’s website and the transaction is either accepted or rejected based on the information that is received. At all times the secured connection does not allow any unauthorized access to the information that is being transmitted and received.
