What is a Payment Gateway ِAnd How It Work Exactly?

Ever questioned how online businesses process online payments?

If the answer is yes, read on.

We are going to investigate payment gateways: The technology used in an online store and provide useful information for when you are setting up your e-commerce business.

So, the point here is that processing debit or credit card payments is simple when done in brick and mortar; you present your credit card and it gets processed at a POS terminal, and your transaction is complete.

However, since e-commerce transactions are completed over the internet, there’s no way a customer can physically present their card.

But when it comes to online payment, e-commerce transactions are not done the same way, as you cannot physically present your credit card to process the payment. Instead, you deal with a digital equivalent to a POS terminal, hence the introduction of a payment gateway.

What is a Payment Gateway?

A payment gateway is what authorizes and deal with debit/credit card payments for online retailers. This could be realized by encryption of sensitive data and sending it between a portal (Like a website or a mobile app) and the bank or the front-end processing entity.

How Does a Payment Gateway Work?

The function of a payment gateway is making the communication between a website, payment processor and the bank that issued the credit card used in the buying process. One very important feature of the credit card is the security, manifested in the encryption of the transaction data between the merchant and the issuing bank.

Although it happens within few seconds only, there are a number of steps that take place; the customer is asked to visit a secure payment page where the transaction data is input and encrypted to be sent to the payment processor through the gateway.

The payment processor then communicates with the card-issuing bank, which replies with either an approval or a decline. Such a reply then arrives at the payment gateway which forwards it to the website. Finally, the information shall be interpreted into a response that appears on the transaction window. If approved, the online merchant shall fulfill the order.

How secure are payment gateways?

It’s crucial that you maintain the highest kind of security before asking your customers to input their card data. Data security is important as to prevent breaches that could be highly threatening to both your customers and your business.

Luckily, payment gateway providers take security quite seriously.

Reputable payment gateway suppliers will be level 1 compliant with the Payment Card Industry Data Security Standard (PCI DSS).

Highly prestigious payment gateway developers should be level 1 compliant with Payment Card Industry Data Security (PCI DSS) which is the strictest standard out there and require many security routines and assessments.

Are payment gateways susceptible to fraud?

Payment gateways can be more secure than Fort Knox but that won’t necessarily protect you from fraudulent transactions.

Payment gateways can be extremely secure, but that doesn’t mean that fraudulent transactions won’t be possible.

The good news is payment gateways typically come with dozens of configurable fraud prevention tools. There’s far too many to talk about in detail so we’ve picked out three popular tools you may have heard of.

But rest assured, for payment gateways normally are prepared with a lot of fraud prevention tools. Here are some of them.

The first is 3-D secure. Which is the name of security protocols provided and operated by card networks. Visa uses Verified by Visa, Mastercard’ uses SecureCode, American Express uses Safekey and so on.

The details vary depending on the network, but it works by entering an additional password separate from their password for the website if the password doesn’t match the records registered in the network, the transaction will be then declined. Such an additional test is to make sure that the customer is the cardholder and not someone who has stolen the card or hacked the account.

Second, velocity checks by IP address. This tool basically keeps track of how many times a particular IP address has been used to place an order. If one IP address attempts to place a dozen different orders with a dozen different credit cards in the space of one hour, it’s highly likely that a fraudster is working through a pile of stolen cards.

The second tool, velocity, verifies the activity via IP; it tracks how many times an IP has attempted to place an order. If such IP was observed to be placing so many orders with a lot of different credit cards within one hour, the IP will be blocked for a certain period of time.

The third tool we have is location blocking, as certain countries have higher fraudulent incidents more than others, such as developing economies. So, if for example your business is in one place and you receive a lot of transactions, say from a country in Africa, it’s more likely to be a fraudulent attempt.
