As all of us know that credit cards are the new mode of making payments in both online and offline transactions, it becomes necessary for every merchant account to be able to accept credit card payments. This is possible because of services like payment gateway and merchant account. With the payment gateway credit card information of the people who wish to pay to you by credit card is processed. The gateway processes the card and shifts the money from the credit account of the customer to you r merchant account. In short the merchant account is the point where all payments made to you by credit card are collected.
