Design and implementation of RFID-based anti-theft system

High value assets loss due to theft can be reduced if the attempt to remove the asset is detected at once. This paper study the design of anti-theft system based on RFID technology. The RFID tag that attaches to an object is integrated with motion sensor. The interrupt function is utilized to the tag to automatically detect motion of an object. The real-time notification of theft is realized using multi-communication principle between a tag and a reader. The anti-theft system proposed here was tested for motion detection efficiency and RF communication performance in multi-floored building to verify its reliability.
