Integration & Implementation Methods link


The birth of cloud integration was a game changer. It revolutionized the way businesses approach integration and the age-old battle against data silos. Offering flexibility and scalability, cloud integration opened a world of new opportunities for organizations to connect disparate systems. Businesses have benefited greatly from the ability to combine all of their cloud applications in addition to on-premises systems. This practice gives companies comprehensive access and visibility into their data as well as improved functional connectivity.


Semi-integration is a measure that ensures payment terminals are connected with retail point-of-sale software, while maintaining separation between payment information transmission and other systems. To enable retailers to become PCI compliant without extensive investment into fully integrated compliant systems, semi-integration offers a cost effective, compliant resolution.


In this scenario, the entire payment system is within the merchant's owned and maintained infrastructure. The POS machines, the terminals, the servers, the firewalls - everything. The entire system is also within PCI scope. Any change in a part of the system affects the other parts. They are all connected and communicating with each other as a whole point of sale and payment processing environment.


Standalone payment solutions are disconnected from the point-of-sale payment system, and do not communicate with additional software. Transactions are completed directly through the payment device and payment network, but do not offer the added benefits of transaction automation and reconciled reporting.

AppLink is used to electronically submit merchant application data to our back-end systems to automate the merchant underwriting and onboarding workflow. Pull customer data from existing CRM systems or build your own custom user-interface to quickly capture and complete a merchant application.

Nuvei merchants have access to our powerful online reporting portal, also available for integration to third-party financial software. It provides businesses with timely, critical information, analytics and social media reviews, plus 24/7 self-service support. All this, from an elegant, simple to use dashboard.

SaaS vendors, marketplaces, apps and platforms — enable seamless payments via API or a hosted enrollment page.

Our advanced eCommerce payment technology enables our Partners to offer virtually every type of online payment — from major credit cards and UnionPay International PIN debit and credit, to mobile wallets and alternative payments.

Perfect for cloud or tablet-based POS systems, cloud POS integration offers additional cost savings due to reduced complexity. Integration is quick and simple, with our support specialists always standing by to assist our Partners and their merchants.

Semi-integrated solutions require less development and offer a faster time to market. As with full integration, it provides faster checkout times that can improve customer satisfaction. Plus, it makes management easier as it allows merchants to perform checkout functions more smoothly and efficiently.

Benefit from robust and proven payment systems. Since the POS software solution is also integrated into other back-office applications such as the merchant’s accounting system or CRM, payment integration assists merchants in enhancing efficiency and productivity in processing payments, plus reporting and reconciliation.
