This Final Project documentation guides the reader through a complete product development process. The goal was to design and build a low-cost battery-powered, portable device capable of reading ISO (International Organization for Standardization) compliant animal identification implants, along with a mobile application for further user friendly interfacing.
After the discussion of the RFID (Radio Frequency Identification) systems in general, and the relevant ISO 11784 és 11785 standards in detail, the design process of the circuit is presented, starting from selecting what components to use, right until the assembly of the manufactured PCB (Printed Circuit Board). In addition, the code used to process the data on the transponder and to perform the CRC (Cyclic Redundancy Check) is described, as well as other embedded software elements (user interface, Bluetooth communication). Furthermore, the project contains the building of an Android application for real life operation, which based on the received ID, collects data from the Hungarian Veterinary Chamber's database about the animal and displays it.
