QR-payments. Simplified.

Two mobile applications (B2B and B2C) that help consumers and businesses use mobile transactions. P2P transactions in applications are implemented via QR-codes on mobile devices.

briefly

We were working on the development of an ecosystem of two applications: B2B and B2C. B2B application is intended for sellers, and B2C is for buyers. Applications should provide convenient and secure use of mobile transactions both for companies and for individuals. Moreover, the payments had to be implemented using QR codes within the mVisa technology.

challenge

Usually, the companies dealing with payment systems have lots of vendors, and this project is not an exception: mobile applications must meet the needs of different companies, because the client works with both the largest European retailers and small horeca companies. Lots of stakeholders, different goals, very little time. We had to fulfill the needs of end users that don’t want to pay with cash (that’s one!). Small horeca-companies, that can’t afford payment terminals, and therefore a mobile solution would fit perfectly — that’s two!

DONE

B2B Application

While working on the interface design, we implemented Visa guidelines and combined them with the best local practices and patterns. Local solutions helped us understand the patterns and flows that are familiar to users in the application, at the same time we cut off the cases that wouldn’t work on the Ukrainian market. While designing the B2B application, we implemented the needs of both large retailers and small retail chains — beauty salons, coffee houses, and diners. Having a variety of feedback, we compiled and prioritized the backlog, estimated by three criteria: importance for end users, importance for business, complexity of implementation.

B2C Application

While working on the B2C app, we had to make sure that the interface will be simple, easy to use and secure. Decades will pass, and the main values of any financial service will remain safety and security: all processes must be transparent, all patterns are clear, the possibility of accidental errors is minimized, the security of personal data and user account are carefully worked out and tested.

Results

In the shortest possible time — 5 months — we developed mobile applications for B2B and B2C segments. By implementing prototypes and quickly responding to changes in requests, we saved a significant share of resources and time, and non-standard architectural solutions provided the flexibility of the developed applications. Module structures are universal, thus our solutions can be used as single applications, connected to any Visa partner applications or linked to various types of applications.

" The nullgravity team has proven to be highly professional, flexible, scalable and very competent technically. They often deliver results faster than even we are able to keep up with."

Simple. Transparent. Reliable.

While working on the B2C app, we had to make sure that the interface will be simple, easy to use and secure. Decades will pass, and the main values of any financial service will remain safety and security: all processes must be transparent, all patterns are clear, the possibility of accidental errors is minimized, the security of personal data and user account are carefully worked out and tested.

Think fast. Act right. Move forward.

To speed up the decision-making process, we didn’t just invite key representatives of business departments to all meetings, but also representatives of the technical team. Because of that, we were able to close several stages of product development with one meeting. While presenting detailed prototypes of interfaces, we discussed both business needs and technical details of the implementation, even though such details are usually thought through during the development process.
