Constrained by operating system or device choice?
NMI is OS and device agnostic. We believe you shouldn’t be limited because you develop in a particular language or need to use a particular device. We offer choice in OS compatibility, payment devices, and acquirer connections. Whether you’re developing software for ecommerce, retail card present, or integrating payments into unattended terminals, you’ll have greater freedom with NMI than with any other gateway.
