As they planned to expand their business globally, a European mobile banking service provider approached QArea with a request to test the quality of their hardware and software systems.

Our main task was to conduct a thorough check of their hardware terminal. Specifically, its connection to the mobile application. The mobile POS system was intended to be used by millions of businesses across Europe, so our job was to make sure that the systems are robust and configuration reliable.

It was also necessary to ensure that every step of receiving a payment through the mobile POS system is intuitive — from connecting the hardware to confirming a transaction.
