Ⅰ. Introduction
Ⅰ-1. Motive and Purpose
-Ubiquitous Trend of RFID (Radio Frequency Identification) can replace the barcode system. So it has emerged as a major area of ubiquitous and has been being utilized in many uses due to the high efficiency and several benefits. So our team wants to analyze and get a deep understanding about general RFID system through existed case studies.
