Best 20 International Payment Gateway For Online Business In 2021

An international payment gateway is a middleman between your online store and the payment processor that receives the payment from your customer. In other words, once a customer enters their payment details on your site, the payment gateway takes care of sending that data securely to the payment processor.

An international payment gateway takes care of authorizing the payment and ensuring that the data entered is enough to finalize the payment. The gateway protects the details of the credit card by encrypting all sensitive information it holds. This process ensures that personal private details are passed securely between the customer and the merchant.


Why We Use Payment Gateway For Online Business

Using an international payment gateway can help decrease the frequency and severity of credit card fraud within the e-commerce business. A payment gateway allows the merchants to process credit, debit, and other alternative online payments. The payment gateway acts as the go-between to make sure that customer data is encrypted and secure. There are some reasons for using an international payment gateway.

Setting up an international payment gateway is very easy for a merchant who already has an account and website. It also requires little maintenance. Since most online retailers use an international payment gateway, it will be easy for merchants because most online shoppers are already familiar with the technology.

Using a payment gateway also allows the customers to stay at merchants’ sites without the trouble of popping up to new pages. Merchants can control and customize their checkout pages which is an advantage for them.


How Does A Payment Gateway Work

  • Hosted payment page

A hosted payment page is an out-of-the-box payment page where customers are redirected when they are ready to checkout. The international payment gateway securely receives the transaction data before it passes it to the acquirer. A hosted payment page reduces the PCI burden for online merchants if you don’t collect and store the cardholder data on your server.

  • Server-to-server integration

A server to server integration is also known as a direct integration as it enables the communication between two servers; the merchant’s server with the payment gateway’s server. By requesting the card details on the payment page, a direct transaction can be initiated. Customers can finalize a card payment without being redirected to the payment page of the payment gateway, resulting in faster checkout, a more consistent user experience, and more control over the look and feel of the payment page from the merchant’s perspective. A server-to-server integration is suitable for collecting and storing the payment data before sending them to the an international payment gateway for processing.

  • Client-side encryption

Client-side encryption, also known as encryption-at-source, refers to encrypting sensitive on the client-side device before sending it to the merchant’s server. It enables the merchant to simplify your PCI compliance requirements. In a nutshell, it enables you to accept payments on your website while encrypting card data in your browser, using the an international payment gateway encryption library.


What Is A Merchant Account

A merchant account is a specific bank account required for card payments / online trading. Not to be confused with the business bank account, though. Payment gateways, payment service providers (PSPs), acquirers, payment processors, independent sales organizations, or high street banks can provide you with a merchant account. Once your application for a merchant account is approved, you will be assigned a merchant identification number.


Payment Gateway vs. Merchant Account

You need to have a merchant account to accept card payments and use an international payment gateway to transmit online payment data. You’re PSP, an international payment gateway, or any other financial institution that processes your payments, as previously mentioned, can issue your merchant account. The bottom line is, you can’t accept online payments without having a merchant account.
