Online payment processing
 

Every merchant who interacts with online payments in one way or another has heard of a payment gateway. A payment gateway is a technology that allows merchants to securely accept and process online transactions. We can compare it to a regular POS terminal that merchants use to accept debit/credit cards in brick-and-mortar stores. Like a POS terminal, the gateway is designed to transfer payment information between all parties involved in a transaction, but is used specifically for processing online payments. Thus, every retailer who wants to accept online payments needs a payment gateway for selling products that will protect their customers' sensitive information from fraud through data security tools such as encryption, SSL, and tokenization.
