Diploma thesis presents development and implementation of flexible RFID reader. Based on physical properties, frequency band, and different codding modes of RFID systems we propose teoretical system which can be used on all of the wide usage specter of RFID technology. Developed prototype supports reading of tags on 125 kHz frequency band with ampitude modulation of data. Process of development and implementation of prototype is presented in detail. The main part of the thesis is focused on program-based decoding of signal with microcontroller 16F628A. Prototype detects and decodes a tag and displays its identification number.
