Web platform for connecting POS systems and payment gateways

This bachelor thesis deals with the design and implementation of a web application for businesses in the gastronomy industry. The proposed software enables the optimization of ordering and payment processes by connecting POS systems with selected payment gateways using REST API. The thesis first analyzes the current ordering and payment processes in restaurants and bistros. It then focuses on the payment methods accepted in these establishments and the payment gateways available on the Czech market. Next, it examines POS solutions for gastronomy businesses and existing options for automating the ordering and payment process. The thesis shows that businesses in this sector are faced with traffic problems during rush hours. A stand-alone POS system is not sufficient to optimize operations. The analysis also reveals that traditional payment methods such as cash, credit cards and meal vouchers are still popular in the gastronomy industry. The introduction of payment gateways is not as common in this area. The proposed web application is designed as a modern Single Page Application using a three-layer client-server architecture. The entire development uses JavaScript technologies such as Node.js, React and MongoDB database. The result is an application solution through which customers can order and pay for food at selected restaurants and bistros without the need for a waiter. The app can also represent a new sales channel for B2C businesses in the industry.
