In today’s digital world, online payments have become a crucial part of businesses. Whether it’s e-commerce, financial services, or subscription-based platforms, a secure and seamless payment process is essential. This is where a payment gateway comes into play.
A payment gateway is a technology that facilitates online transactions by securely transferring payment data between a website or app and a bank. In this guide, we will explore how a payment gateway works, its key components, benefits, and why businesses need it.
What is a Payment Gateway?
A payment gateway is a technology that allows businesses to accept online payments securely by processing credit cards, debit cards, UPI, net banking, and other digital payment methods. It acts as a bridge between customers, merchants, and financial institutions to authorize and complete transactions in real time.
Types of Payment Gateways
1. Hosted Payment Gateways
Redirect customers to a third-party payment page. These are easy to integrate but may affect user experience.
2. Self-Hosted Payment Gateways
Allow customers to enter payment details directly on the merchant’s website, offering greater control over the user experience.
3. API-Integrated Payment Gateways
Use APIs to process transactions directly on the website or app without redirecting users. These provide seamless transactions and are widely used in e-commerce platforms.
4. Bank Payment Gateways
Offered directly by banks for businesses that want to process payments without third-party involvement.
Understanding How a Payment Gateway Works
Step 1: Integrating a Payment Gateway
Once your online store is live, the initial step is incorporating a payment gateway to facilitate secure transactions. This ensures that both merchants and customers can process payments safely and transparently.
To integrate a payment gateway, choose a provider and link it to your website’s checkout process. You can configure it to support multiple payment options based on your business requirements.
Step 2: Customer Redirection to Payment Gateway
When a customer proceeds to checkout, they are redirected to the payment gateway. Here, they enter payment details such as card credentials or UPI ID.
- Data Encryption & Fraud Checks: The gateway encrypts payment details to maintain security and conducts fraud detection checks.
- Transaction Processing: It transmits transaction data to the acquiring bank, which then communicates with the card network (e.g., Visa, Mastercard) and the issuing bank for approval.
- Fraud Detection: Advanced security measures like IP tracking, pattern recognition, and AI-driven fraud checks help detect suspicious activities.
Step 3: Transaction Authorization & Bank Response
Once the acquiring bank receives the transaction request, it verifies the details to confirm authenticity.
- Issuing Bank Review: The acquiring bank forwards the request to the issuing bank, which determines whether the transaction should be approved or declined.
- Customer Notification: The payment gateway informs the merchant about the transaction status. The customer is then redirected to view the outcome:
- Approved Transactions: A confirmation message with order details is displayed.
- Declined Transactions: Customers are asked to retry using an alternate payment method.
This process happens in real time, ensuring a seamless user experience.
Step 4: Payment Settlement
After a successful payment authorization, the acquiring bank initiates the settlement process. The payment gateway collects funds from the issuing bank and transfers them to the merchant, typically within a few business days.
Upon completion, the customer receives a confirmation that their order has been successfully placed.
Difference Between Payment Gateway & Payment Processor
Payment gateways and payment processors are essential components of electronic financial transactions, particularly in e-commerce. However, they serve distinct functions. Here’s a breakdown of their differences:
Payment Gateway
Role
A payment gateway acts as a bridge between the customer, the business, and their financial institutions during an online transaction. It securely transmits sensitive payment information and facilitates transaction authorization.
Main Functions
- Encrypts transaction data for security.
- Forwards transaction details to the business’s acquiring bank or payment processor.
- Receives the transaction approval or decline response.
- Communicates the transaction status to the business’s website or app.
Security
Payment gateways use security measures to protect against fraudulent transactions and ensure payment data security. These include:
- Encryption protocols (SSL or TLS)
- Fraud detection algorithms
- Address Verification System (AVS) and Card Verification Value (CVV) checks
Integration
Payment gateways integrate with e-commerce platforms, websites, or mobile apps via APIs or prebuilt plugins, ensuring smooth transaction processing.
Payment Processor
Role
A payment processor, also known as a merchant services provider, handles transaction processing. It manages the authorization and settlement of funds between the customer’s issuing bank, the business’s acquiring bank, and the relevant payment networks (e.g., Visa, Mastercard).
Main Functions
- Verifies transaction details.
- Checks the customer’s account balance and payment method validity.
- Approves or declines the transaction.
- Facilitates the transfer of funds between the customer’s and the business’s accounts during settlement.
Security
While payment gateways primarily verify transactions and prevent fraud at the point of sale, payment processors ensure the highest security standards for payment data. They comply with PCI DSS requirements, ensuring secure handling and storage of cardholder information.
Relationship with the Business
Payment processors often have a direct contractual agreement with businesses, providing them with a merchant account. This specialized bank account enables businesses to accept and process electronic payments securely.
Difference Between a Payment Gateway and a Payment Terminal
Payment gateways and payment terminals both enable payment processing, but they serve different transaction environments and methods. Here’s a breakdown of their key differences:
Transaction Environment
Payment Gateway
A payment gateway is primarily designed for online transactions, catering to e-commerce websites, mobile applications, and other digital platforms.
Payment Terminal
Also known as a point-of-sale (POS) terminal or credit card terminal, a payment terminal is a physical device used in brick-and-mortar stores, restaurants, and other in-person retail environments. It enables customers to make payments using credit cards, debit cards, or contactless payment methods such as smartphones with near-field communication (NFC) technology.
While payment gateways are mainly used for online transactions, some providers offer integration options that allow them to support in-person payments in retail environments.
Payment Processing
Payment Gateway
A payment gateway acts as an intermediary between the customer, the business, and their respective financial institutions during an online transaction. It encrypts sensitive data, facilitates transaction authorization, and streamlines fund settlements.
Payment Terminal
A payment terminal performs similar functions to a payment gateway but is designed for in-person transactions. It reads the customer’s payment card or contactless device, communicates with financial institutions for transaction authorization, and prints receipts. It connects to the business’s acquiring bank or payment processor through a phone line, internet connection, or mobile network.
Security Measures
Payment Gateway
To ensure the security of online transactions, payment gateways use encryption protocols such as Secure Sockets Layer (SSL) or Transport Layer Security (TLS), fraud detection algorithms, Address Verification System (AVS) checks, and Card Verification Value (CVV) checks.
Payment Terminal
Like payment gateways, payment terminals employ encryption for card data and comply with Payment Card Industry Data Security Standard (PCI DSS) requirements. Additionally, they support security features for card-present transactions, such as EMV chip technology, which adds an extra layer of protection against fraud.
Integration
Payment Gateway
Integrating a payment gateway into an e-commerce platform, website, or mobile app often requires technical expertise, API implementation, or the use of pre-built plugins.
Payment Terminal
Setting up a payment terminal is typically simpler, involving the physical installation of the device and connecting it to the business’s POS system, internet, or phone line.
