    The thesis describes the development of an application for the mobile platform Android mEuroBillTracker that enables data entry about banknotes, review of entered banknotes and their map display. The application is based on the web application EuroBillTracker that enables registered users also review and entry of new banknotes. Since the manual entry of banknote data is time comsuming the aim of the thesis was to develop an application that would accelerate the complete data entry process. At the same the possibility of mistakes would be reduced through an automatic entry of specific fields. There are some similar applications that accelerate the data entry process to some extent, yet none of them enables the capture and recognition of the serial number. Therefore the main emphasis was on the entry of the serial number that was captured with a camera, processed with computer vision methods and finally underwent the optical character recognition process. For the optical character recognition to be successful it is very important that the entry image is as sharp as possible. Therefore we implemented a system of continuous auto focusing while using the accelerometer. With its help we were able to define the moment when the device stopped and only then we triggered further optical character recognition. The next sensor used was the global positioning system which gave us the data about the current location. On its basis and with the help of the reverse geocoding system we acquired the data about the place, post office and the country of the current location.
