What precisely is a payment gateway? If your e-commerce consumer has “filled their shopping basket” and clicked the link that says “Go forward to checkout” or “Complete order”, your shopping basket software will estimate his or her amount spent, including any added fees, discounts, credits, along with taxes. The resultant final amount is what he or she needs to pay out … But how? The common way is either a MasterCard or credit card (like PayPal along with bank-issued, American-Express Card or other electronic cards). Now you should verify that the buyer holds this card, is up-to-date with the card provider and, with regards to a debit-card, has enough funds to settle the transaction or, when it comes to a credit-card, has enough credit.

The money gateway is a software that processes this MasterCard or credit card details. This program connects with a payment merchant, who manages the actual business of notifying the VisaCard or credit card service and directs the payment. The payment processor will send the details to the card company to deduct that total from the cardholder’s sum or charge his / her account. In its work, it is much the same as the credit card device you’ll see in several bricks-and-mortar outlets, where the buyer swipes his/her visa card through the gadget and, when it is a debit-card, types in a PIN number.

The details transmitted to the money gateway would be encrypted with a Secure Socket Layer normally known as SSL encryption. The consumers details will have been typed in by HTTPS protocol, also protected.

Also there is something called V. P. A. (Virtual Payer Authentication). This is “Validated by VISA” and could be the most popular brand. This brings one more layer of safety for the service provider.

A new system, 3-D Secure, is available as further support in verifying the identification of the client for the vendor, since merchant and client cannot see each other and may actually be separated by seas or even be located in different states.

The whole verification operation takes only some seconds. (Can you remember the old days, earlier than e-commerce, when even a shop transaction involving a bank card could take a lot of minutes to validate?)

As the debit card or VisaCard usage has been authenticated, the transaction is concluded and the buyer is free to navigate close the website, assured that his/her goods will be mailed shortly and that her credit card data is safe.
