Introduction

Point-of-sale (POS) systems have been a part of the organizational structure of retail and service businesses as tools that help with sales and stock control. Earlier POS systems were much more extensive, involving cash registers supported by numerous formalities that, in most cases, created confusion. However, with the years of progress, these systems have been adapted from a technological viewpoint, thus bringing forth the mobility approach in POS solutions. The knowledge of this evolution can help firms comprehend the current state of the technological landscape and apply it to the maximum advantage of mobile POS solutions. The modern POS systems use wireless communication, cloud computing, and advanced software to provide organizational flexibility and efficiency. Mobile POS systems assist transaction processes in becoming more efficient and contribute to overall customer satisfaction because of increased efficiency and individual attention. This paper analyses the transition from traditional to mobile POS, looking into the factors that have forced the change, the problems experienced, and the gains accrued to businesses and consumers.
