Colorimeter for Medical Applications with NFC Connections
Šobich, Adam ; Čížek, Martin (referee) ; Sekora, Jiří (advisor)
This Master’s thesis deals with assembling of a colorimeter using NFC technology. The theoretical part introduces the principles of colorimetric measurement, calibration curve, and important physical quantities. Further, the principle of NFC technology, its architecture, and division of NFC devices are described. The goal of the practical part is to propose a structural design and software solution of a colorimeter. Particular emphasis is placed on the selection of the RGB sensor that is being tested and its results are being analyzed. The construction of electrical circuit and microprocessor control are being solved. The manuscript deals with the implementation of an application for the Android operating system, which serves as the user interface of the colorimeter. Obtaining data from the sensor and storing it in a memory of the NFC tag is provided by the Arduino platform. Issues that were encountered during the work are analyzed in the discussion.

Mobile phone payments in developed and developing countries
Obšivačová, Ivana ; Křížek, Tomáš (advisor) ; Baran, Jaroslav (referee)
The bachelor thesis focuses on the topic of mobile phone payments within direct banking services. Theoretical part offers basic description of the currently-in-use direct banking products. This paper also characterises mobile phone payment systems in developing countries, their fundamental conditions, problems with their implementation and outlines M-PESA as an example of a successful system. The next section analyses mobile phone payment system in developed countries defining conditions and presumptions for mobile phone payments in order of becoming appropriate competitor to the cash payments. To summarize, at the end there is a comparison of the mobile phone payment systems in both, developed as well as developing countries emphasizing on the main differences.
