How Payment Gateways Secure your Online Transactions

by August 3, 2015 0 comments

The utility of payment gateways can’t be ignored in today’s time where internet is the key of everything. Here are the technologies they use to secure your transactions and a hands-on demo to setup the oldest and most popular payment gateway

A payment gateway is an online platform that provides a secure connection to carry out the transaction process between an e-commerce entity and the internet merchant account. It verifies, accepts or declines the transactions in real time on a merchant’s behalf through secure Internet connections.
The payment gateways form the basis of online transactions. If you own an online store, then without a payment gateway, you cannot sell your products and services to your customers. You need a secure and speedy channel that allows you to process credit card and electronic check payments of your customers. And if you are a customer and wish to buy something online, then you have to do it through a payment gateway only.

The steps involved in an ecommerce transaction:
1.    A customer purchases an item and enters his card details in the e-commerce checkout.
2.    Details about the purchase are sent by e-commerce checkout to the payment gateway for processing.
3.    The payment gateway forwards transaction information to the seller’s bank.
4.    The seller’s bank forwards transaction information to the bank that issued the buyer’s card to authorize the transaction.
5.    The bank that issued the buyer’s card verifies the buyer’s card details and either approves or denies the transaction and sends that information back to the seller’s bank.
6.    If the transaction is approved, the bank will deposit funds on a merchant’s account at a scheduled time.
7.    The payment gateway sends transaction details and response back to the e-commerce entity.
8.    E-commerce service then lets the buyer know if the transaction was approved or denied.
Is your money in safe hands?
Buying stuff online is easy, saves time and money, however there’s a risk involved. Each time we pay for something, we input our credit/debit card details to a third party (other than our bank). And considering the virtuality of online medium and the risks associated with it, there’s always a sense of fear for online fraud. However, these e-commerce platforms and banks tend to maintain a robust framework to securely carry out the transactions for the goods and services we pay for.
Let’s check out some of the security methods used by payment gateways to safeguard customer’s money:
Data Encryption
Data encryption is one of the main security method used in payment gateways. Once you enter your card details in the payment gateway, it gets encrypted by using payment gateway’s public key and can only be decrypted by the payment gateway’s private key. The gateway uses an algorithm which makes sure that no unauthorized party can decrypt the encrypted data when being transmitted through the network. These algorithms usually follow symmetric (same key for encryption and decryption) or asymmetric (different key for encryption and decryption) cryptography to mask data so that unauthorised sources are unable to read or intercept it.
Secure Socket Layer (SSL)
Secure Socket Layer (SSL) is the standard security protocol used in online transactions to establish an encrypted link between a web server (where the payment is taken) and a browser (where the payment information is entered). E-commerce websites uses SSL to authenticate their identity to the visiting customers and to protect sensitive information such as card details entered by the customers. It is advisable to make an online transaction on websites which have SSL certification. You can check out the same for a website by noting the https prefix in the URL address of the website in the browser and by locating the Padlock symbol in the web browser.
Secure Electronic Transaction (SET)
Developed by Visa and MasterCard, the Secure electronic transaction (SET) protocol is used to aid the secure transmission of customer’s credit/debit card details during online transactions. The protocol blocks out the details of credit card information, thus preventing merchants, hackers and unauthorized parties from accessing the sensitive information. SET uses customer digital signatures to maintain confidentiality, authentication and data integrity
