Gateway compatibility
The payment gateway consists of software installed on Web servers to facilitate payment transactions. The gateway software captures credit card details from the customer and then verifies the validity of the credit card with the transaction clearinghouse.
Gateways are complex because they can create compatibility problems. In turn, these problems make e-commerce transactions unreliable. So, the entrepreneur needs to consult experienced developers before investing in a payment gateway. Therefore, before launching the site, online pilot testing must be done to test the reliability of the gateway.
