More Choice, Simplified Security and Compliance
We support a wide range of payment devices, certified with multiple payment processors, ensuring your merchants always get the right solution for their needs. The card readers we support meet all payments industry directives and many offer PCI validated P2PE to minimize the PCI compliance burden.
Parking and EV Charging
NMI is the easiest way for parking and EV charging station operators to accept card payments. Whether on paystations, meters and kiosks, or app-powered solutions, NMI makes integrating card and phone payments simple. We offer a range of payment devices, each certified with leading acquirers and bank processors. Integrating payment devices is fast and easy using our refined SDKs and APIs — there’s no need for specialized developers with payments expertise.
Transportation and Tolls
Cashless payment is a core feature in any transit system, and NMI has been powering innovation in transit payments for over 10 years. We support transit ticketing providers with gateway and secure tokenization services for both traditional ticket vending machines and new Open Loop fare collection systems. Use our SDKs to easily integrate a range of transit-specific payment devices, each certified with one or more leading acquirers and bank processors for fast deployment.
Vending and Kiosks
Contactless payment has become the standard now for low value self-service vending and kiosks, and cards are widely preferred over cash. NMI offers reliable, frictionless card acceptance that meets the specific needs of the vending and kiosk industries, and again provides choice when it comes to both payment devices and acquirer/processors. Easy-to-integrate SDKs and APIs make adding cashless payments to virtually any type of vending machine or kiosk fast and simple.

From self-serve supermarket checkout lanes to the new breed of unattended retail stores, NMI has the fast, secure payment options to support the future of physical retailing. Supporting industry-standard retail payment devices and offering the flexibility to integrate app and QR code payment into the mix.
Complete Unattended Solutions for Merchants of All Types and Sizes
NMI Gateway
If you or your merchants already have a preferred processor, the NMI Gateway is the ideal choice to power your unattended offerings.
Pre-Certified Hardware
All of our supported payment devices are certified for use with the industry’s top processors and acquirers, making it fast and easy to get your merchants set up with the right hardware choice for their needs.
APIs and SDKs
NMI offers a variety of developer tools designed to make designing, testing and deploying custom unattended solutions faster and easier than ever. Our APIs and SDKs make it simple to integrate our hardware devices and the NMI Gateway, and our Developer Portal offers a complete set of resources and a visual design toolkit to help you unlock the full power of our payment solutions.
Security and Fraud Prevention
By their nature, unattended environments are at higher risk of fraud and malicious attacks than attended checkouts, making security even more important. With optional PCI-validated point-to-point encryption (PCI P2PE) NMI is committed to ensuring you can offer your merchants the most secure unattended payments available today. That not only keeps you and your merchants safe, it also helps to reduce compliance headaches.
Premium Support
When unattended systems go down, there may not be anyone on site to immediately notice or resolve the problem. That makes maximizing reliability and uptime critical parts of offering great service to your merchants. NMI offers you a partner with decades of experience as a leader in unattended payments, and the best tiered support the industry has to offer. That enables you to keep your merchants processing without interruption and to ensure issues are dealt with quickly when they do arise.
