In today's world, consumers increasingly value convenience and comfort during their shopping activities, placing emphasis not only on store location and variety of products but, most importantly, on saving time and having positive shopping experiences. On the other hand, from the perspective of retail chains, the growing number of customers brings a host of additional challenges. Long checkout lines that cause customer frustration and the need to hire extra staff, along with the associated costs, are just a few examples. Addressing these issues for both shoppers and stores is the Polish startup ZeroQs, developed by Jarosław Kaczmarczyk's team.
