Abstract: In today’s world, more and more often you can find the saying that the machine, or robot, replaces man in his field. This can be seen in many areas of human life, but a special niche for machines to occupy in self-service systems. These systems are quite a popular solution in the field of sales of goods and services, because for such a business you do not need to hire a seller, pay him a salary and tax to the state. Although such devices are quite expensive, they are a good alternative in terms of convenience for the buyer and pay off quickly for the owners. Payment in self-service terminals is made using a special device - a bill acceptor. But there is an alternative to monetary transactions - non-cash payment. [2] The first option has several disadvantages: the lack of ease of use, the size of a large number of bills, the possibility of loss or theft of securities. That is why non- cash payment methods have become widely used. They allow a user who has certain electronic hardware (bank card, built-in NFC module in the phone, RFID key) to use their funds extremely conveniently and securely, which is what most people prefer.[3] Cyber-physical systems are systems that combine advances in various fields of science, such as automation, computer networks, metrology, information security, computing, and more. Vending systems combine sensors, specialized equipment, monitoring systems, payments, etc. These systems interact with each other using most standardized Internet protocols. In addition, thanks to the Internet, it configures and monitors such systems. [1] 7 The cashless payment module is one of the most important parts of the self- service system. This module allows you to conduct non-cash financial transactions using special physical devices, which is many times more convenient than banknotes. In addition, thanks to the remote server, the system becomes scalable, which allows you to connect as many modules as needed. The object of research is vending cyberphysical systems with the ability to perform non-cash payments. The subject of the work is the study of the module of non-cash payment for self- service systems. The purpose of the study is to analyze the main ways to implement the module of non-cash payment, the elemental basis on which this module will be implemented, the solution of which is more rational and cost-effective implement this type of system. And also make a reliable server and database for processing and storing customer data and conducting transactions. This paper considers ready-made non-cash payment systems in this area. Their comparative analysis is made, the main advantages and disadvantages of existing analogues of this system are defined. Various methods of realization of the module of non-cash payment are offered. One of them has been developed, namely a cashless payment module based on a microcontroller, as well as a server for receiving information from this module and making payments by customers.
