This thesis talks about planning a project which includes construction of functional prototype of a mobile and modular station for bike sharing system. The first part focuses on theoretical background of significant concepts for working of such systems. The thesis then describes hardware and software used in the project. Main part of the thesis focuses on developing graphical user interface and writing a program for programmable logic controller, while they represent the major part of functionality of the system. The whole prototype was appropriately tested. Last part describes results of the project and further upgrading possibilities.
