Recent development in online payments demonstrates the importance of payment gateways for your organization. Payment gateways are services that handle card transactions for your company. They are an advantage to your organization since they enable secure and efficient transactions and decrease losses due to late payments. A payment gateway facilitates online payments for consumers and companies, hence facilitating the payments ecosystem. If you’re an online merchant, you don’t need to be an expert in payment gateways in the USA, but it’s beneficial to have a basic grasp of how an online payment moves from your client to your bank account.

What Is A Payment Gateway?

What is a payment gateway

The system that “captures” and “transfers” payment data from a client to an acquirer, and then “transfers” the payment acceptance or refuse status back to the customer, is referred to as a “payment gateway.” A payment gateway is a third-party service that verifies the customer’s credit card information, verifies that sufficient funds are available, and ultimately makes it possible for merchants to get paid. It functions as an interface between the website of a merchant and the acquirer for that business. It protects the customer’s sensitive credit card information by encrypting it and guaranteeing that it is safely sent from the merchant to the acquiring bank on the customer’s behalf.

To put it another way, the payment gateway acts as a go-between for the client and the merchant, ensuring that the transaction is carried out in a timely and secure manner within the e-commerce stores. The process of merchants integrating the appropriate software may be made easier by using online payment gateways in USA. The gateway acts as an intermediary between the acquirer and the merchant during the processing of payments and is responsible for managing the sensitive card information of customers.

How Does A Payment Gateway Work?

The consumer selects the desired product or service and goes to the payment page. Most payment gateways provide several customization options for the payment page. emerchantpay’s payment gateway provides the following choices for your business-specific payment page:

Hosted payment page

A hosted payment page is a pre-built payment page to which consumers are forwarded when they are ready to complete their purchase on their e-commerce stores. The payment gateway receives the transaction data in a secure manner before transmitting it to the acquirer. If you do not collect or keep cardholder data on your server, a hosted payment page decreases the PCI compliance burden for e-commerce stores.

Integration of two servers

A server to server integration is sometimes referred to as a direct integration since it facilitates communication between two servers: the server of the merchant and the server of the payment gateway. By asking card information on the payment page, a transaction may be started immediately. Merchants have greater say over the design and layout of the payment page since customers don’t have to leave their site to complete card payments, which speeds up the checkout process and improves the user experience. If you gather and/or keep payment information before transferring it to the payment gateway for processing, a server-to-server interface is appropriate.

Client-side encryption

Client-side encryption, also known as encryption-at-source, involves encrypting sensitive data on the client-side device prior to transferring it to the server of the merchant. This facilitates the simplification of PCI compliance requirements for the merchant. In a word, it lets you take payments from customers directly on your site while protecting their credit card information using the payment gateway’s own encryption library.

On the payment screen, the consumer enters their credit or debit card information. These contain the cardholder’s name, the card’s expiry date, and the CVV number (Card Verification Value). Based on your integration, this data is sent to your payment gateway in a safe manner.

Before sending card data to the acquiring bank, the payment gateway tokenizes or encrypts the card information and conducts fraud checks. The acquiring bank transmits the information to the card schemes in a safe manner (Visa, Mastercard). The card schemes then submit the payment data to the issuing bank after a second level of fraud screening. After undertaking fraud screening, the issuing bank authorizes the transaction. The accepted or denied payment notification is returned to the acquirer from the card schemes.

The acquiring bank returns an approve or deny message to the payment gateway, which then forwards it to the merchant. If the transaction is accepted, the acquirer gets the payment amount from the issuing bank and keeps it in your merchant account.

The process of depositing the funds into the merchant’s account is known as settlement. Depending on the terms of the merchant’s agreement with their payment gateway, the settlement will take place at a certain time. Depending on the message, the merchant may either show a payment confirmation page or request an alternative payment method from the consumer.
