Parking facility payment terminal in eight weeks with AI-assisted development

Finnpark is a Finnish parking company that designs and delivers smart parking services to make movement easier, as well as providing commercial premises for parking and business needs. Finnpark’s services span everything from equipment supply to comprehensive parking management across Finland.

Finnpark’s goal was to build a new physical payment terminal for a new car park and integrate the Adyen payment system, all within eight weeks. The project was also a step towards a broader ambition: to build a solution that could later be rolled out to other locations.

The payment terminal was designed with the user at the centre. The car park serves a diverse range of customers, and the payment journey needed to work smoothly for everyone, without registration or a separate app. The interface had to be clear and consistent enough that users always know what to do next, and the process never stalls due to confusion.

An eight-week timeline is tight for any project, but particularly demanding when you are simultaneously building a physical device, deploying a new back-end system, and constructing a working payment infrastructure.

Qvik was responsible for building the point-of-sale application on an Android device, covering UI design, software development, and coordinating between multiple parties alongside the client. The project drew on Qvik’s deep expertise in AI-assisted development, with nearly all programming carried out using AI agents, enabling both rapid progress and high quality.

“It was clear that the development had to be agent-based in order to meet the ambitious timeline. It simply wouldn’t have been possible the traditional way. That said, when you’re dealing with payment transactions, quality and security have to be guaranteed.” Tuukka Vauramo, Co-founder, Qvik

The AI generated code and resolved bugs, but decision-making, requirements definition, quality assurance, and project management remained firmly in human hands. Qvik’s years of deep experience in transactions and payments meant the team could identify potential risks early and address them before they became problems.

Within the first few days of the project, a working prototype was ready, covering all the core functionality, which was reviewed together with the client. From there, the final product and system integrations were developed in parallel across several workstreams, with the different components brought together into a complete, functioning solution towards the end of the project.

The UI design didn’t start from a blank slate. Pain points in previous solutions were mapped carefully, customer service staff were interviewed, and user feedback was collected systematically to ensure the design was grounded in real user needs. The result is a payment journey that flows naturally, without interruption.

There were very few surprises during the project, a significant achievement given the tight schedule, and since go-live, payments have worked without issues. The modern system has a more resilient architecture than its predecessor and is better equipped to meet future needs.

A user-centred, intuitive interface with built-in guidance reduces the volume of support contacts: when the payment journey is straightforward, customers simply need less help.

Because Adyen is already used across Finnpark’s other payment flows, extending it to physical terminals brings all payment activity together into one unified system. The terminal requires no registration, no app, and no manual entry of card details, making it particularly well suited to occasional users and significantly lowering the barrier to payment.

Qvik has a proven process for payment integrations: an efficient, AI-assisted, and reliable approach to building physical payment solutions. This expertise can be applied wherever payment terminals need to be deployed quickly, without compromising on quality.
