We participated in the creation of a payment system for a regional network comprising several thousand terminals, which was subsequently sold to a larger conglomerate. By far the most common task in these kinds of projects is the integration of a web application into an existing payment system. The company has carried out projects such as these many dozens of times, examining the API of all major global payment systems. In addition, we gained expertise in writing low-level software for all kinds of devices, including for the drivers of card readers, touchscreens and keyboards. Developing a graphic interface for payment terminals is not a complicated task, with the major difficulties arising in the writing of code for peripheral devices, especially where it is necessary to write a new driver for hardware.
