The gateway provides an interface between the merchant and the bank's payment processing system. The payment gateway translates messages into other message formats (for example, VisaNet) that are used for the authorization and settlement of merchant transactions. Payment gateway takes a transaction, then certifies it and routes it after securing it with encryption. It also manages the translation and decryption. Almost all payment gateways are based on Secure Electronic Transaction (SET) technology, a system to ensure the security of financial transactions on the Net. Master Card, Visa, Microsoft, Netscape, and others supported it initially. Our on-line payment approach gives your e-business entry option, with room to grow the business. By implementing this solution, the customer will be able to use their credit card / debit cards on the e-commerce portal sites to make payments.
