Merchant providers are the go-between service that connects everything behind the scenes. Providers connect to the credit card network, thousands of issuing banks, and your banking services. To ensure the utmost security, most credit card processors are PCI-compliant and use advanced encryption methods. To select the right credit card processing services, it’s essential to review your current or projected credit card payment volume and where customers pay (online, at your cash register, or via mobile devices). Then compare companies by looking at how much you’ll pay for processing while assessing customer support and extra services.
