Around the world millions of people buy products or services in physical stores and online. At the same time, millions of merchants, traders are looking for new tools to increase sales, reach an increasing number of customers and above all build loyalty. Every year, millions of merchants spend over $ 20 billion on software which provides loyalty systems and rewards for their customers. The motivation behind this is that they have to offer additional services to remain
competitive in the market. Loyalty programs, however, as they are structured today, do not work as they should. For traders they often turn out to be expensive and difficult to set up. For buyers they are dispersive and not convenient.
