A payment gateway is an e-commerce application service provider service that authorizes and executes e-transfer of money in successful manner with great accuracy ratio. It is equivalent of a physical point of sale terminal located in most retail outlets. Payment gateways protect your confidential credit/debit/shopping card details by encrypting sensitive information, such as credit card numbers, to ensure that information is passed securely between the customer and the merchant and also between merchant and the payment processor. All of the payment gateway sites nowadays provide “https:” protocol (SSL) which is considered as a secure protocol on internet.

Through Payment gateways, you can connect your online shop to any major payment processor, bank or card association. A payment gateway facilitates the transfer of information between a payment portal like a payment website/ a mobile phone/an IVR service and the Front End Processor/ acquiring bank. When a customer orders a product from a payment gateway-enabled merchant, the payment gateway performs a variety of tasks to process the payment transaction.

Reputed payment gateways have come up with great security measures as the customer is usually required to enter personal details like login id, passwords, and card numbers. To validate the request of the payment page result, sometimes IP of the requesting server has to be verified. There is a growing support by acquirers, issuers and subsequently by payment gateways for Virtual Payer Authentication (VPA), implemented as 3-D secure protocol – branded as Verified by VISA, MasterCard SecureCode and J/Secure by JCB, which adds additional layer of security for online payments. 3-D Secure promises to lighten some of the problems facing online merchants, like the inherent distance between the seller and the buyer, and the inability of the first to easily confirm the identity of the second.
