What is a payment gateway?
A payment gateway is a solution that connects your bank account with a merchandising platform to which you wish to transfer money. It creates a secure tunnel between online retailers and buyers.
Most of eCommerce service providers create a website with payment options as it is a fundamental feature offered to their clients. It allows us to make purchases anywhere in the world while ensuring maximum data security.
Payment gateways are virtual terminals equivalent to physical point-of-sale terminals.
How does a payment gateway work?
A payment gateway is an important broker between customers and merchants. It is dealing with payment processing and authorizing. Payment gateways deliver an encryption method to sensitive data like credit card numbers. The data is encoded giving you a guarantee that it is sent securely between the online store and the customer.
Here is a basic flow of the transaction:
- a customer finishes an order by clicking a submit button or its equivalent
- the customer is redirected to a payment gateway allowing him/her to choose credit card payments or to be redirected to a bank website. The transaction is transferred to the issuing bank or another page like 3Dsecure to authenticate the transaction
- if the authentication is successful the bank checks if the customer has enough funds on his/her account to make a response to the payment gateway that the transaction is a success or not
- when the response from the bank is ready, it goes to the merchant. If the answer is negative, the merchant will display a notification about an error to the user. If it is positive, the merchant seeks the transaction from the bank
- in the end, the bank settles the payment with the payment gateway, which settles the money with the merchant
The key points that any payment gateway provided are authorization, settlement and reporting.
