Understanding Online Payment Gateways
What Are Online Payment Gateways?
Online payment gateways are digital services that help e-commerce businesses in the US accept payments from customers over the internet. Think of them as the virtual cash registers for your online store. They act as a bridge between your website, your customer’s bank or credit card company, and your own business bank account.
How Do Online Payment Gateways Work?
The process is simple, but it involves several steps to keep everything secure and smooth. Here’s a step-by-step breakdown:
| Step | What Happens |
|---|---|
| 1. Customer Checks Out | Your customer chooses products and heads to checkout on your website. |
| 2. Payment Info Entered | The customer enters their payment details (credit card, debit card, PayPal, etc.). |
| 3. Data Encryption | The gateway encrypts this sensitive info to protect it during transfer. |
| 4. Payment Authorization | The payment gateway sends the info to the payment processor and then to the customer’s bank/card network for approval. |
| 5. Approval/Decline | The bank/card network approves or declines the transaction based on available funds and security checks. |
| 6. Transaction Complete | If approved, funds move from the customer’s account to your merchant account, and both parties get confirmation. |
