The article investigates the system for contactless payments using NFC technology. The practice of acquiring as a method of trade that increases the attractiveness of the business for the client and simplifies the process of trade for owners and employees. The relevance of such a system in Ukraine and prospects for its development are determined.
The availability of such systems on the market, combinations of systems that allow to obtain the same attractiveness for business and customers are analyzed. Although such systems attract customers to the business, the number of services that can provide relevant services to the customer or business remains small, and ready-made solutions that combine functionality for both customer and seller have not yet been found. The aim of the article is to present the stages of development of contactless payment systems that transfer data between client applications using NFC technology and a server based on microservice architecture.
The article presents a system of contactless payments based on NFC technology, its structure and algorithm. It is stated that the principle of operation is to receive and transmit data from two end customers of the system to one of the payment systems in a certain order, which allows secure execution of payment transactions.
