Independent thesis Advanced level (professional degree), 20 credits / 30 HE credits
The purpose of this master thesis was to develop an intelligent name card with use of RFID technology, wireless transmission of information.
While the master thesis I studied different RFID standards to find an appropriate standard. I chose the ISO 15693 standard for it's simplicity and it's cheap, unfortunately it not have the highest memory capacity of the different standards.
Next part of the thesis was to program the graphical user interface, and together with a RFID reader be able to read and write to the transponder. Unfortunately I have not got the serial interface (RS-232) to work, instead I have simulate the Reader with the command shell (DOS-window).
When develop the GUI I chose to use java because to make the program platform independent.
The last part was to propose the hardware, it basically consist of three parts: a micro controller, a transceiver chip and an antenna. The microcontroller is used for interface and buffer between the host computer and the transceiver chip. The transceiver chip converts the data signals to radio signals and controls the transmission. The antenna can be printed on the circuit board.
The RFID tags on the market today have not enough memory to store pictures.
