Security is one of the most important things to consider when looking at credit card payment processing. Consumers who visit your site want to know their information will be kept safe and that they are not at risk of identity theft or any other type of credit card fraud.
When choosing a payment processor, the first thing you should look for is whether they utilize Secure Sockets Layer (SSL). SSL is a protocol developed to protect sensitive information being passed between web browsers and web servers and is the industry standard technology for data encryption.SSL ensures that data reaches the intended recipient only and is vital to e-commerce solutions. A page that uses SSL can be identified by ‘https’ at the start of the address, or by the lock symbol displayed at the bottom of the browser window.
Leading payment processors use SSL with an encryption key length of 128 bits, which is the highest level of security commercially available.
Another thing that falls under the banner of security is credit card fraud prevention. As a merchant you are ultimately liable for any fraud that occurs through your site – as such it is vital that your payment processor has extensive measures in place to reduce fraudulent transactions.
