Payment Gateways
A payment gateway is an e-commerce application service provider (ASP) that authorizes credit card or direct payment processing for e-businesses, online retailers, or traditional brick and mortar businesses. It facilitates the transfer of information between a payment portal (such as a website, mobile phone, or interactive voice response service) and the front-end processor or acquiring bank.
History
The concept of electronic payment processing can be traced back to the early days of electronic funds transfer (EFT) in the late 1960s and early 1970s. However, the development of payment gateways as we know them today took off with the advent of the internet and e-commerce. The first online payment gateway, known as First Data, was established in 1971, but it was not until the mid-1990s that the use of payment gateways became widespread with companies like CyberSource and Authorize.Net entering the market.
Functionality
- Transaction Security: Payment gateways employ various methods to secure transaction data, including encryption, tokenization, and adherence to standards like PCI DSS (Payment Card Industry Data Security Standard).
- Authorization: When a customer submits their payment details, the gateway forwards this data to the issuing bank or card association for approval.
- Payment Processing: If the transaction is approved, the gateway ensures funds are transferred from the buyer's account to the merchant's account.
- Settlement: The gateway communicates with the merchant's bank to finalize the transfer of funds.
- Reporting: Provides detailed reports and analytics on transactions for merchants.
Types of Payment Gateways
- Hosted Payment Gateways: Customers are redirected to the payment provider's website to complete the transaction (e.g., PayPal).
- Self-hosted Payment Gateways: Transactions occur on the merchant's website, offering more control over the payment process and branding.
- API/Integrated Payment Gateways: Offer integration through APIs, allowing for a seamless checkout experience directly on the merchant's platform.
