Payments for parking

NMI is a leading provider of card payment solutions in the parking industry. We understand the challenges faced by equipment manufacturers and operators alike. Using our wide range of pre-certified card-present solutions is the easiest way for parking operators and manufacturers to accept card payments and access advanced features such as card-in/card-out, PCI P2PE, pay by QR code, and in-app payments. Integrating payment devices is fast and easy using either our refined SDKs, simple APIs or all-in-one solutions — there’s no need for highly skilled developers with payments expertise.

NMI offers reliable, frictionless and easy-to-integrate card acceptance solutions for vending, kiosks, EV charging and tolls. With more deployments globally than any other gateway in these fields, NMI brings a breadth of experience and a toolkit like no other. Choose from a variety of payment devices from leading manufacturers, each certified with major processors and acquirers. Our SDKs and APIs make it fast and simple to add full chip and PIN, PIN on glass or contactless-only payments to your terminals. NMI’s solutions can share communications with existing telemetry and integrate transaction reporting into your back-office systems.
Payments for transportation ticketing

Cashless payment is a core feature in any transit or ticketing system, and NMI has deep experience powering innovation in transit payments. We support ticketing providers with gateway and secure tokenisation services for both traditional ticket vending machines and new open-loop fare collection systems. Integrators can use our SDKs to easily integrate a range of EMV payment devices, each certified with one or more leading acquirers and bank processors and most with support for PCI P2PE.
