Payment Gateway: What It Is, How It Works, the Best Gateways Compared
The average eCommerce shopping cart abandonment rate is 69.57%. A good payment gateway can decrease that number, thus getting you more conversions.
We will cover what a payment gateway is, how it works, and the differences from a payment processor. We will also review the best payment gateways in the industry.
What Is a Payment Gateway?
A payment gateway is a portal that connects a bank account to the relevant payment processor. It transmits transaction information either virtually through web payment services and APIs or in-person through a payment terminal.
This payment service authorizes different modes of online transactions such as internet banking, credit cards, UPI (Unified Payments Interface), and other forms of digital wallets.
eCommerce businesses need a payment gateway as it ensures secure payments and protects sensitive data. Customers can safely store their essential information, like credit card details in the Payment Card Industry Data Security Standard (PCI-DSS) portal.
Many payment gateways also come with fraud screening tools, including CVV (Card Verification Value), AVS (Address Verification Service), and payer authentication, to reduce the risk of information loss and theft.
Some payment gateways also support cross-border online payments, making it easier for aspiring business owners to scale their eCommerce at the international level.
How Does a Payment Gateway Work?
In every online transaction, there are four key parties. Besides the buyer and the merchant, there’s also the issuing bank (who issued the customer’s card) and the acquiring bank (who collects the funds from the issuing bank).
Though there are a lot of steps, digital transactions usually take minutes.
Once a customer is ready to proceed to checkout, the website will direct them to a payment gateway to enter credit card information or bank details.
The next step is encryption. The payment gateway will then encode exclusive data to use between the buyer and the seller.
Additionally, the gateway will perform fraud checks with built-in security protocols, namely TLS (Transport Layer Security).
After ensuring a safe connection, the issuing bank will then check if there is a sufficient balance in the account.
The payment processor will contact the merchant account. If authorized, the acquirer collects and then settles the balance into the merchant account. The customer will finally receive a notification of their successful transaction.
If the merchant account denies the transaction, the seller will ask the customer to opt for another payment method. Some of the factors that influence the approval include network errors, the upper limit on the merchant’s transactions, and bank-related issues.
Difference Between a Payment Gateway and a Payment Processor
While a payment gateway and a payment processor go hand in hand during a transaction, both are completely different and not interchangeable.
A payment processor is a liaison that communicates transaction information between the merchant, issuing bank, and acquiring bank. Its role is to maintain the security of payment processing, from user authentication to fund settlement.
Typically, a payment processor also supplies credit card machines or other equipment to accept payments. For this, you will need a merchant account alongside a service provider.
In brick-and-mortar purchases, a payment processor will use a terminal as its point of sale interface.
On the other hand, a payment gateway explicitly acts as the middleman between the buyer and seller.
If a payment processor is for card-present transactions, a payment gateway facilitates transactions where a card doesn’t have to be present. It’s a point of sale terminal for your online business.
As there is no customer or credit card physically present, the virtual authentication process is more sensitive. Payment gateways have the task to validate customers’ digital credentials against malicious threats to make the payments secure.
Types of Payment Gateways
Since it’s important to have a good payment gateway, knowing the pros and cons of each type will help you choose.
Redirection
The most simple checkout experience, redirection, is best for new and small businesses as they are secure and easy to set up. Sellers don’t need to create a merchant account to configure them.
This payment gateway will take your customer to a separate payment page to complete the transaction. On the checkout screen, you can promote your brand by displaying your logo.
With third-party redirect gateways, you can rely on them to do the heavy lifting – from security protocols to privacy liabilities. However, this can also pose as a disadvantage, as you’ll have less control over the process.
Another downside is that this method may interrupt user shopping experience. The buyer will need to leave the eCommerce site to complete the online payment.
On-Site Checkout, Off-Site Payment
The checkout process is done on-site, without any redirects, thus streamlining the user experience.
However, to finish a transaction, this gateway will take customers off-site. Meaning, sellers need to ensure security themselves.
Your website must establish PCI compliance to protect customer information, which requires more resources and technical expertise.
On-Site Checkout and Payment
This type of payment is ideal for large eCommerce businesses that are expecting to generate a high volume of sales. From checkout to payment processing, everything will work through the seller’s system.
A third-party gateway will temporarily redirect your customer off-site for the transaction. However, they won’t realize this as the hosted payment page looks exactly like your eCommerce website.
During this process, you can offer special deals or take advantage of the add-ons to push people into buying more items.
Once the transaction goes through, the system will automatically transfer users back to your site. This way, customers can continue surfing the product pages, giving you more chances to increase conversions.
While this payment method provides a fast, secure, and reliable transaction, it has quite a complicated infrastructure. You will need advanced technical knowledge or hire a developer to set it up.
On-site payment comes with abundant responsibilities as you are in control of everything. Alongside the payment gateway itself, you’ll need an SSL certificate and PCI compliance.
Examples of the Best Payment Gateways Available for eCommerce Businesses
Considering the importance of having a payment gateway for online stores, it’s essential that you pick the right payment gateway provider.
We have compiled a list of top-ranking payment gateway providers based on their ease of use, security, cost, and compatibility.
1. PayPal
You may recognize PayPal as one of the most widely-known payment gateways supporting both money transfers and transactions. It offers two types of payment methods — PayPal Payments Standard and PayPal Express Checkout.
The PayPal Payments Standard lets merchants accept credit cards online, while the PayPal Express Checkout redirects customers to log in to their PayPal account to complete their transactions.
The latter streamlines the payment process as customers don’t need to input their payment information every time they purchase an item.
Pros:

- Helpful features. These include fraud protection, 24/7 phone support, and shopping cart integrations — all of which are compatible with most eCommerce platforms.
- Cross-border payments. PayPal is one of the most used payment providers around the world.
Cons:
- Interrupted shopping experience. As PayPal uses redirection, customers must go to another web page to complete their payments. The auto-return feature is only available for business accounts.

Owing to the mobile payment structure, Apple Pay lets buyers make purchases using Face ID and Touch ID.
As long as your store provides an NFC terminal, you can accept credit cards and other electronic payments with this service.
Pros:
- Business chat. The anonymized digital token system makes Apple Pay one of the most secure payment solutions.
- Effortless checkout. The contactless system provides a fast checkout process compared to other credit card payments.
