Studies have shown that you can increase your business sales manifold if you accept credit card payments from your customers. This is because most people are not like to carry cash around, and so using their debit card or credit card is their preferred mode of payment. Suppose, you own an online store where people can make orders by the click of the mouse. It follows naturally that you should be also in a position to accept credit card payments online. Then there may be situations where the people would prefer to make their orders by phone. There are companies that give a toll free number and the people can place their orders and give their credit card information based on voice prompts.

To accept credit card payments, you need to have an online merchant account with any financial institution, bank, or acquiring institutions. These institutions will deposit the money accepted through a website into your account. Apart from getting a merchant account, you must also get a payment gateway. As the name itself suggests, the payment gateway is a gateway, actually a code, which processes and validates the credit card information by sending the information provided to the credit card company and gets an accept or decline message. On getting the accept message, the gateway then transmits the amount from the website to the merchant account.

Address verification is the most important aspect of credit card services, as it is essential to fight against credit card fraud. Some credit card companies ask for the CID or the credit card identification digits.

Software such as the IC Verify (DOS winpopup), PCAuthorize (Windows), or MacAuthorize (Mac) These software are required to process the credit cards.

As a merchant, you can accept credit card information on your own website or on the website of the acquiring institutions, with whom you have your merchant account. These institutions charge a nominal fee for their services, but the increase in sales is well worth the investment.
