On having an internet store or retail e-commerce website, you will require online credit card processing. Online merchant account and credit card payment gateway together can provide your customers an option to purchase goods any time and anywhere, with a click of the mouse.
Here is a brief description of how online credit card processing actually works. The online customer interested in purchasing product or service from merchant searches and reaches the concerned merchant s website. Through merchant s website, customer does purchase and before leaving the website enters their billing information. For any payment to be done online, security is must.
If merchant s website is not having secured webpage then the customer is to be transferred to secured payment gateway. If merchant s website is a secured one then without leaving the site, the billing information of the customer is passed on to the payment gateway, which is further transmitted to the processor. The processor passes the billing information received from online payment gateway onto the credit card issuer bank. The issuer bank verifies the validity of the card and whether the amount requested on card is available or not. Once the requested amount by the customer is available, the bank set aside that amount for the merchant and sends back an approval number; otherwise a decline message is sent by the issuer bank to the processor which in turn passes back to merchant s site.
