Cloud Integration

Sound Payments’ unique integration method makes it easier for ISVs and merchants to interface to Cloud Solutions. This innovative way of connecting register and register systems to terminal devices greatly reduces time involved with development and quality assurance. This also removes the need for end-to-end certifications.


Our solutions allow for connection to any device that has Internet support, regardless of the type of connection. Our simple API (application programming interface) is designed to hide the complexity of transaction processing in the new age of EMV. With sensitive data not reaching the register, the PCI scope is reduced. Only data allowed is shared from the terminal device to the register.


The combination of these solutions improves how merchants conduct business at a price that is financially feasible.
